I am trying to compile an existing qt application's code using mingw compiler.
During compilation I am getting an error "*** internal error: unable to open jobserver semaphore '3,4': (Error 2: The system cannot find the file specified. ). Stop".
My current project is a makefile based project. Here I have one make file (parent.mk) that compiles all primary modules and then
parent.mk
compilation steps
.
.
.
make $QT_CODE_DIR
Here in this QT code directory I have another makefile (child.mk) which has following content:
child.mk
cd "qtcode_compilation_out_dir"
qmake.exe "product.pro" -r -spec win32-g++
CONFIG+=release
mingw32-make -w
If I try to run the make command manually for QT code then it works fine.
#Alexander: Thanks for the suggestion.
Please suggest if anyone has any idea about it.
Thanks.
Finally, I found out the exact reason of the problem and solution as well.
Reason for failure:
The compilation command that I am using is "make" which is been aliased to "make -j2"and along with "mingw32-make -w" it was producing the error because mingw32-make is an obsolete make command and it doesn't support multi threaded compilation.
Solution:
I just replaced the mingw32-make with make.

I did a clean install of MinGW on Windows 7 32bit with the GUI Installer, and installed
ming32-base-bin
mingw32-gcc-g++-bin
msys-base-bin
When trying to compile a simple "Hello World.cpp" from the cmd.exe i get the error:
C:\Users\Lorenzo\Desktop>g++ "Hello World.cpp" -o"Hello World.exe" -m32
g++: fatal error: cannot execute 'cc1plus': CreateProcess: No such file or directory.
compilation terminated.
The weird thing is that by grabbing the file from the desktop and putting it over g++.exe (so that i open the file with the application) in the MinGW directory, i don't get any error.
A temporary fix i found was to have a new environmet variable pointing in the folder where cc1plus is (C:\MinGW\libexec\gcc\mingw32\9.2.0). The program runs but doesn't include the libraries from C:/MinGw/lib and C:/MinGw/Include, i have to include those manually, which shouldn't occur (i guess).
I don't want to do this crude fix since i know i'll encounter some other problems with time.
Ok. I found the solution with some luck.
It is as simple as adding .exe to g++
> g++.exe *input file* -o*output.exe*
Don't Know if it's a bug or not, but this works for me.
I'm not sure which MinGW you used exactly, but it's better to use MinGW-w64.
There is a standalone build you can get from http://winlibs.com/ that doesn't require installation. The site also gives some instructions on how to use it.
I run gradle to build an android .aar and it reports that it can't find a file, but the file definitely is there.

Could anyone help? I am kind of running out of ideas on this.
I discovered it was because I had 'caseSensitive' flags enabled on some of my directories. Be careful, this is a new feature of WSL2 and there are some peculiarities where you may be enabled in without realizing. Windows cmake cannot traverse directories that have this flag enabled on them.
Read about it here:

I am trying to build u-boot
Toolchain:
http://web.archive.org/web/20130823131954/http://www.angstrom-distribution.org/toolchains/
U-boot: git.denx.de
I am following this site to build this u-boot
http://beagleboard.org/linux
It says to put cross compiler path before building.
export PATH=/usr/local/angstrom/arm/bin:$PATH
1) I can see angstrom folder in /usr/local. Also I think that we need the toolchain's actual place of binaries. Let suppose in /home/myhome/BBB/angtrom_x_y_z/usr/local/angstrom/arm/bin
So which path actually i should export?
2)I have tried to put both paths, but I am getting errors.
3)I have downloaded three toolchains
angstrom-2011.03-i686-linux-armv5te-linux-gnueabi-toolchain
angstrom-2011.03-x86_64-linux-armv7a-linux-gnueabi-toolchain-qte-4.6.3
angstrom-2011.03-i686-linux-armv7a-linux-gnueabi-toolchain-qte-4.6.3
1st gives errors as
CROSS_COMPILE=arm-angstrom-linux-gnueabi- make am335x_evm
scripts/kconfig/conf --silentoldconfig Kconfig
CHK include/config.h
GEN include/autoconf.mk
arm-angstrom-linux-gnueabi-gcc: 0: No such file or directory
arm-angstrom-linux-gnueabi-gcc: unrecognized option '-G'
cc1: error: unrecognized command line option "-mabicalls"
make[1]: *** [include/autoconf.mk] Error 1
make: *** No rule to make target `am335x_evm'. Stop.
second one is I think for 64 bit processor, I have i386 one, so it also doesn't worked
Third one is corrupted.
Can anybody tell me how to compile it as the site says. Maybe the site is outdated but still if anybody can tell me a straightforward way how to do this.
It looks like Angstorm toolchian is too old to deal with recent U-Boot. I tried your procedure and get other errors. I'm not sure why you try to use that old toolchain and if you have to use it. But I quickly check Linaro toolchain gcc-linaro-arm-linux-gnueabihf-4.9-2014.07_linux, which I use for boards like Cubietruck and A20-OLinuXino-MICRO and it works fine.
git clone git://git.denx.de/u-boot.git
cd u-boot
export PATH=${PATH}:${PATH_TO_TOOLCHAIN}/gcc-linaro-arm-linux-gnueabihf-4.9-2014.07_linux/bin

I'm currently trying to build the android version of google breakpad on a linux machine. But it seems I'm having some issues getting the stl to be properly referenced.
I get past the configure step running ..
./configure --host=arm-linux-androideabi --disable-processor

For output of this see config.log
My environment has the following variables set ..

When I run make -j4 I get the following errors..
src/client/linux/crash_generation/crash_generation_client.cc:34:21:
fatal error: algorithm: No such file or directory compilation terminated.
There are more similar errors related to stl (full output here). So my question is how do I get this to build with those included. I don't work in linux much so please try to be explicit with any answers.
Thanks
I added the following flags and reran config and then the compile succeeded.
CPPFLAGS=--sysroot=/home/desktop/Development/android-ndk-r9d/platforms/android-9/arch-arm -I /home/desktop/Development/android-ndk-r9d/sources/cxx-stl/stlport/stlport

I am trying to run the netbeans makefile via my terminal of one of my C++ project
While executing
Make
, I receive the following errors:
...
/bin/sh: 1: -o: not found
make[1]: *** [nbproject/qt-Debug.mk] Error 127
...
What should I do? Thanks in advance. Please note that I can easily build the program via Netbeans.
EDIT : I use ubuntu 13.04, netbeans 7.3, linux terminal.
I simply use:
make
or
make CONF=Release
in the project root (where the Makefile is located), and it works. I have a simple C++ project without anything extra.
