Install 32 bit PBC library on 64 bit machine - build

I want to install the PBC library for my project. On my 64 bit system, the configure script installs 64 bit libraries readily. But the code that I have to use is built on 32-bit.
I tried this command (from an answer to this question):
./configure --build=i686-pc-linux-gnu "CFLAGS=-m32" "CXXFLAGS=-m32" "LDFLAGS=-m32"
But I get this error when I run 'make' :

The '--help' lists out the following flags:
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a nonstandard directory <lib dir>
LIBS libraries to pass to the linker, e.g. -l<library>
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if you have headers in a nonstandard directory <include dir>
CPP C preprocessor
Use these variables to override the choices made by `configure' or to help it to find libraries and programs with nonstandard names/locations.


First, check:
./configure --help
does it allow to override CFALGS/LDFLAGS?
If yes, then do it as per the help info.
Second, usually, ./configure produces makefile and then you issue "make" command.
You said, you got this error just after configure ?
If you are getting these errors after make then it
looks like ld is linking with old-residue.
Did you try:
make clean;make


Thanks #Icarus3. You pointed me in the right direction. The command I used was :
./configure --build=i686-pc-linux-gnu "CFLAGS=-m32" "CXXFLAGS=-m32" "LDFLAGS=-m32"
When I ran
./configure --help
it did not have CXXFLAGS. So I changed it to CPPFLAGS=-m32. And it worked.

"/usr/bin/ld: cannot find -llibopencv_calib3d" when compiling an opencv project in Ubuntu 20.04

I have installed opencv in Ubuntu 20.04 following the instructions in OpenCV Installation in Linux. As per the instructions, sudo make install copies all the .so files to /usr/local/lib.
However, when compiling a program, using the command g++ --std c++17 -g opencv/Basic.cpp -o output -I/usr/local/include/opencv4 -L/usr/local/lib/ -llibopencv_calib3d -llibopencv_core -llibopencv_dnn -llibopencv_features2d -llibopencv_flann -llibopencv_highgui -llibopencv_imgcodecs -llibopencv_imgproc -llibopencv_ml -llibopencv_objdetect -llibopencv_photo -llibopencv_stitching -llibopencv_video -llibopencv_videoio I get the following error.
/usr/bin/ld: cannot find -llibopencv_calib3d

collect2: error: ld returned 1 exit status
I have also added a .conf file in /etc/ld.so.conf.d/opencv.conf with the line /usr/local/lib/ and issued the command sudo ldconfig. However, the issue remains.
I'd be grateful for any ideas or suggestions to resolve this issue.

-llibopencv_calib3d
make it
-lopencv_calib3d
etc. the lib part in front of it is simply wrong

OpenCV libraries missing

I'm failing to build a project in c++ where OpenCV is used. Here is what I got:
/usr/bin/ld: cannot find -leigen
/usr/bin/ld: cannot find -lhighgui
/usr/bin/ld: cannot find -lcore
/usr/bin/ld: cannot find -leigen
/usr/bin/ld: cannot find -lhighgui
/usr/bin/ld: cannot find -lcore
But there are only libraries like "-lopencv_core" available nowadays.
Is there any options how to fix this?
I'm using Ubuntu.

How did you install your distribution of OpenCV. The typical way of installing OpenCV is to download git repo and build it yourself.

Undefined symbols for architecture armv7 but lipo -info shows ok

I think you guys have seen this kind of errors before, but mine is special.
I have a few static libs in my Xcode project, when I tried to build it I got this error. But I have checked all my libs with command xcrun -sdk iphoneos lipo -info $libname, it gave me Architectures in the fat file: /Users/kiwi/Documents/Development/SourceCode/prj/lib.a are: armv7 i386 x86_64 arm64.

make: *** [MyProject] Error 1`
I have included libraries and their paths in the following ways.
Project–>Properties
In C/C++ Build ->Settings.
In GCC C++ Compiler ->Includes.
In Include paths(-l) I have added /usr/local/include/opencv.
In GCC C++ Linker
I have added the path (-L) as /usr/local/lib and also library names.
Can anyone please tell me what the reason for this errors?

you have to add the library names without the prefix 'lib'

Symbols not found error when linking iPhone app in Xcode

Whenever I try to compile my iPhone app which i am porting I get linking errors. The app uses a scripting language called Squirrel (to read the level files, fine by the SDK, no user input). I have linked all the libraries including libsquirrel.a. What am I doing wrong?
(App is SuperTux, source code at supertux.lethargik.org for computer version).

Something strange might be going on with libstdc++-static.a. Not even sure what it is.

C++filt is your friend it will unmangle those names to show you what is missing:
> c++filt __ZN9Scripting24create_squirrel_instanceEP4SQVMPNS_12AmbientSoundEb
Scripting::create_squirrel_instance(SQVM*, Scripting::AmbientSound*, bool)
The first line from above seems to indicate that it can't find the definition of the method create_squirrel_instace from the class Scripting.
So the order the libraries are presented to g++ (which is the compiler used on a mac) is important. So have a look at the build output and see if you can find the line where the libraries are linked:
It should look like this:
g++ <STUFF> -l<lib1> -l<lib2> etc.
I reformated the abovre output so it is readable:
In the text I replace
/Users/Thomas/Documents/iPhone Dev Projects./SuperTux with <DIR> to help readability:
A whole bunch of the libraries are not being used becuase they are the wrong architecture:
