I am using this to set the PKG_CONFIG_PATH
export PKG_CONFIG_PATH=/usr/local/dbus/lib/pkgconfig
after this I am trying to run the configure of qt using the following command
./configure -prefix /home/navani/Qt-4.6.3/qt-everywhere-opensource-src-4.6.3 \
-opensource -embedded arm -platform qws/linux-x86-g++ -confirm-license -release \

-no-audio-backend -no-phonon -no-phonon-backend -no-webkit -no-scripttools \
-no-sql-sqlite -nomake tools -svg -script
But I am getting an error saying
PKG_CONFIG_PATH has not been set. This could mean the host compiler's
.pc files will be used. This is probably not what you want.
Am I doing something wrong?? What should I do?

Suppose
You have a module with several public functions exported to the kernel space by EXPORT_SYMBOL
Your other module depends on the abovesaid symbols
Before you would have made a custom Module.symvers containing information about the exported symbols from your first module. It was loaded in the build process and the modpost script worked correctly.
Since 5.6.?? linux kernels this practice changed and it quietly ignores Module.symvers placed in the build directory.
What is the new way to do this thing? I checked that if I add the symbols from my parent module to the system Module.symvers file the dependent module builds, but this is not a long term solution.
P.S.: As for the difference: compare (Linux 5.4.**)
MODPOST = scripts/mod/modpost \
$(if $(CONFIG_MODVERSIONS),-m) \
$(if $(CONFIG_MODULE_SRCVERSION_ALL),-a) \
$(if $(KBUILD_EXTMOD),-i,-o) $(kernelsymfile) \
->here is it-> $(if $(KBUILD_EXTMOD),-I $(modulesymfile)) \
$(if $(KBUILD_EXTMOD),$(addprefix -e ,$(KBUILD_EXTRA_SYMBOLS))) \
$(if $(KBUILD_EXTMOD),-o $(modulesymfile)) \
$(if $(CONFIG_SECTION_MISMATCH_WARN_ONLY),,-E) \
$(if $(KBUILD_MODPOST_WARN),-w) \
$(if $(filter nsdeps,$(MAKECMDGOALS)),-d)
To Linux 5.6.**
MODPOST = scripts/mod/modpost \
$(if $(CONFIG_MODVERSIONS),-m) \
$(if $(CONFIG_MODULE_SRCVERSION_ALL),-a) \
$(if $(KBUILD_EXTMOD),-i,-o) $(kernelsymfile) \

How can I solve this?
why this is not done? I made the build file properly but this is not done?
I use ubuntu os to build this file.
It comes Unknown option --target-os=android, ignored.
I assume you use a deprecated version of x264, because i succeed compiled the latest version form here https://www.videolan.org/developers/x264.html using the following scripts:

And don't forget to change export variables that i described in armeabi-v7a script.
I'm building an embedded Linux system for ARM, and one of the applications is using CMake:
cmake \
-D CMAKE_C_COMPILER=/opt/arm-toolchain/bin/arm-linux-gnueabihf-gcc \
-D CMAKE_BUILD_TYPE=Release \
-D CMAKE_SYSTEM_NAME=Linux \
-D CMAKE_INSTALL_PREFIX=/mnt/system_rootfs ../app_src_dir
If CMake is executed like this, it searches the whole file system for libraries, header files etc.
How can I restrict CMake to ONLY search /opt/arm-toolchain and /mnt/system_rootfs for header files, libraries and programs?
Build system is Debian Wheezy and CMake version is 2.8.9
You can use CMAKE_INCLUDE_PATH and CMAKE_LIBRARY_PATH environment variable for searching header files, libraries.
cmake \
-D CMAKE_C_COMPILER=/opt/arm-toolchain/bin/arm-linux-gnueabihf-gcc \
-D CMAKE_BUILD_TYPE=Release \
-D CMAKE_SYSTEM_NAME=Linux \
-D CMAKE_INSTALL_PREFIX=/mnt/system_rootfs ../app_src_dir
-D CMAKE_INCLUDE_PATH=/include/path
-D CMAKE_LIBRARY_PATH=/lib/path/

Though vim and gvim -u NONE starts fast. Please help me troubleshooting this issue.
