I am trying to use LLVM as backend for my compiler, and while linking with the llvm libraries, I get this error
g++ obj/*.o `llvm-config --ldflags core jit native` `llvm-config --libs core jit native` -lfl -o Icarus
/usr/bin/ld: cannot find -lffi
collect2: ld returned 1 exit status
I have installed llvm on my system and my cpp files compile fine. Its during linking that the library its searching can't be found.
If on a deb system try installing the dev libs, they solved the problem for me:
sudo apt-get install libffi-dev
Hmm. Did you install libffi too?
ftp://sourceware.org/pub/libffi/libffi-3.0.10.tar.gz
I know that installing libffi into /usr prefix helped me, when ld complained about being unable to find -ffi

I am trying compile a software with Scons I get an error saying,
usr/bin/ld: cannot find -lexpat
Can you please tell me how can I fix it? Thank you very much. Here's the full error message:

Below solution worked with me on Ubuntu 20.04:
sudo apt install libexpat-dev
I have had this same problem in Fedora 34. Doing
sudo yum install expat-devel
will solve the problem.
PROBLEM SOLVED:::
I am using LEDA library in c++.
command used to make object file.
g++ -I$LEDAROOT/incl -c mult.cpp
this command runs fine
I am getting eroor while linking step.
HERE IS THE EROOR
varun#Kinley:~/Documents/LEDA/test/numbers$ g++ -L$LEDAROOT mult.o -lleda -lX11 -lm
/usr/bin/ld: cannot find -lX11
collect2: error: ld returned 1 exit status
I think I need to install some package,because when I googled this error the most of problems are solved by installing some package .
I didn't find lx11 error
some of the eroor messages that I googled.
error 1
/usr/bin/ld: cannot find -lfreetype collect2: ld returned 1 exit
status
error 2
/usr/bin/ld: cannot find -lz collect2: ld returned 1 exit status

Do I need to install some package or there is some other problem
Could be two things
1) The X11 library is installed in a non-standard path. Use the search command to see if libX11.a or libX11.so is available on your system. If yes add the directory path to the -L option.
2) You are missing the libX11 library.
In this case, login as admin and use yum (assuming linux) to install this library.
Eg:
"yum install libX11.i386" or "yum install libX11.x86_64", depending on your architecture (32 bit or 64 bit).
I am still having trouble building the Portaudio library on my system, which is OSX 10.7.5 with Xcode 4.3.2, having Command Line Tools installed and having SDK10.6 and SDK10.7 under
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/
I describe shortly (also for others that run into the same problem) what I have done so far (following different solutions I have found on the web).
1) I downloaded "Portaudio" / pa_stable_v19_20111121.tgz (last stable release) from:
www.portaudio.com/download.html
2) I read the instructions on building Portaudio here:
www.portaudio.com/docs/v19-doxydocs/compile_mac_coreaudio.html
and tried to compile from a Terminal window with the suggested command:
./configure && make
This resulted (not so surprisingly) in a lot of errors ending with:
llvm-gcc-4.2: error trying to exec '/usr/bin/../llvm-gcc-4.2/bin/powerpc-apple-darwin11-llvm-gcc-4.2': execvp: No such file or directory
lipo: can't open input file: /var/folders/1_/xkp08ky561jg02zjjrpsxg940000gn/T//ccPxCTrJ.out (No such file or directory)
make: * [src/hostapi/coreaudio/pa_mac_core.lo] Error 1
This happens because "ppc" is not supported anymore since OSX 10.5. Moreover the "Developer" folder doesn't exist on OSX 10.7 and everything that was in the Developer folder has moved to
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/
3) I downloaded a patch (mac_configure_patch.txt) to fix "configure" from:
https://www.assembla.com/spaces/portaudio/tickets/216#/activity/ticket:
and copied it to the portaudio directory and applied it by typing in Terminal:
$ patch < mac_configure_patch.txt
A confirmation message said:
patching file configure.in
So everything seems fine. But still Portaudio is trying to build for "ppc".
4) Now I set the ARCHFLAGS, CFLAGS, LDFLAGS to only build for architecture i386 as follows (disabling universal build):
$ MACOSX_DEPLOYMENT_TARGET="10.7" ARCHFLAGS="-arch i386" CFLAGS="-O2 -g -Wall -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk -arch i386 -mmacosx-version-min=10.7" LDFLAGS="-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sd -arch i386 -mmacosx-version-min=10.7" ./configure --disable-mac-universal
5) Further I found that:
A): "#include AudioToolbox.h" in ".include/pa_mac_core.h" should be UNCOMMENTED
B): that "-wError" from "Makefile" (not Makefile.in) should be removed.
accoding to:
http://www.fluxforge.com/blog/building-portaudio-under-os-x-107-lion
6) Now I try to build (using: "sudo make"), compilation starts but but fails with:
ld: framework not found CoreAudio
collect2: ld returned 1 exit status
make: * [lib/libportaudio.la] Error 1
7) So I try to point to the framework using "-F/System/Library/Frameworks -framework CoreAudio"
leading to the following Terminal command:
$ MACOSX_DEPLOYMENT_TARGET="10.7" ARCHFLAGS="-arch i386" CFLAGS="-O2 -g -Wall -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk -arch i386 -mmacosx-version-min=10.7" LDFLAGS="-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sd -arch i386 -mmacosx-version-min=10.7 -F/System/Library/Frameworks -framework CoreAudio" ./configure --disable-mac-universal
which seems to fix the CoreAudio framework issue but results in another error saying:
ld: library not found for -lSystem
collect2: ld returned 1 exit status
make: * [lib/libportaudio.la] Error 1
I am now stuck at this point. Did anyone experience the same problems when trying to build Portaudio on OSX 10.7 using SDK10.6 or SDK10.7. Did anyone find a solution to how to build Portaudio from Terminal?
I am very thankful for any hints!!!
Thanks in advance!
Try the latest svn. If that doesn't work right off the bat, you might need to muck with some of the flags.
eg, in configure.in:
change -Werror to -Wall
add -Wno-deprecated (you shouldn't need this, but just in case)
then run
./configure --disable-mac-universal
and make as usual.
OK, finally I solved the issue. Hope the solution will help others as well. I just forgot to also add the path to the CoreAudio framework to the CFLAGS. Here is the final configure/build command for building portaudio on OSX 10.7.5 using SDK10.7 for architecture i386 & x86_64:
Open a Terminal window in the portaudio directory and type:
MACOSX_DEPLOYMENT_TARGET="10.7" ARCHFLAGS="-arch i386" CFLAGS="-O2 -g -Wall -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk -arch i386 -mmacosx-version-min=10.7 -F/System/Library/Frameworks -framework CoreAudio" LDFLAGS="-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk -arch i386 -mmacosx-version-min=10.7 -F/System/Library/Frameworks -framework CoreAudio" ./configure --disable-mac-universal
If this has finished, you need to edit Makefile and change the mention of -Werror to -Wall.
Then:
make
Voila. There you have your "libportaudio.la" in the portaudio/lib directory. You can now type
sudo make install
(you'll be asked to confirm using your password)
to put the library in the system directory.
Finally you can mess around with Portaudio!
Have fun!
Tried your instructions on Mac OSX Mountain Lion (10.8), and it was progressing a lot in compilation but then was failing with:
In file included from ./test/patest_sine_channelmaps.c:53:
./include/pa_mac_core.h:100:1: error: unknown type name 'AudioDeviceID'
AudioDeviceID PaMacCore_GetStreamInputDevice( PaStream* s );
^
./include/pa_mac_core.h:109:1: error: unknown type name 'AudioDeviceID'
AudioDeviceID PaMacCore_GetStreamOutputDevice( PaStream* s );
^
2 errors generated.
make: *** [bin/patest_sine_channelmaps] Error 1
However, I figured out you can simply use Homebrew (apt-like packet manager for OSX) and it will do the dirty job like a charm. Find binaries and headers in the specified install directory :)
$ brew install portaudio
Warning: It appears you have MacPorts or Fink installed.
Software installed with other package managers causes known problems for
Homebrew. If a formula fails to build, uninstall MacPorts/Fink and try again.

I got the following error when compiling a simple hello world program on debian amd64 wheezy(testing) with g++ -m32:
/usr/bin/ld: skipping incompatible /usr/lib/x86_64-linux-gnu/gcc/x86_64-linux-gnu/4.6.1/libstdc++.so when searching for -lstdc++
/usr/bin/ld: skipping incompatible /usr/lib/x86_64-linux-gnu/gcc/x86_64-linux-gnu/4.6.1/libstdc++.a when searching for -lstdc++
/usr/bin/ld: cannot find -lstdc++
collect2: ld returned 1 exit status
I don't have any problems with gcc -m32. I also installed lib32stdc++ package, but it does not seem to work. Thanks.
Pretty sure you need to install g++-4.6-multilib (it would appear you already have gcc-4.6-multilib).
Try installing ia32-libs-dev package.
I set up a Ubuntu VM today just to build Festival on Ubuntu (I never ran it before) Then I did the following setups
On the Terminal window I wrote following to install GNU C++ Compiler
sudo apt-get install build-essential
To test the g++ I wrote a sample hello world and compiled it using g++ and run it and it worked as expected.
I downloaded all the files from listed on festival download page
Unpacked all to the home directory(~) using
tar -zxvf *.tar.gz
Then wrote following 3 commands to configure and make speech_tools
cd speech_tools
./configure
make
But make returns with following errors
/lib -leststring -lcurses -ldl -lncurses -lm -lstdc++ -lgcc
/usr/bin/ld: cannot find -lcurses
/usr/bin/ld: cannot find -lncurses
collect2: ld returned 1 exit status
make[1]: *** [ch_lab] Error 1
make: *** [main] Error 2
What am I missing? being a newbie to Ubuntu or any other Unix platform I may missed some important configuration, before that I have successfully built festival on my windows machine using Cygwin.
You probably need to install the development packages for libncurses. Try
sudo apt-get install libncurses5-dev
