cross compiling for qnx

[cy-goh]

Hi I'm trying to cross compile for qnx7 aarch64le from my ubuntu 18.04 environment.

I tried the following configurations. However, during compilation, I seem to be lacking this file .deps/libconfig___la-libconfigcpp.TPlo. I have no experience with libtool and cross compilation so wish someone can help me here.

QNX_BINS="${QNX_HOST}/usr/bin"

./configure CC="${QNX_BINS}/qcc" CXX="${QNX_BINS}/QCC" CFLAGS="-fpic -Vgcc_ntoaarch64le" CXXFLAGS="-fpic -Vgcc_ntoaarch64le -Y_cxx" OS=qnx7 --target=aarch64-qnx-qnx --host=x86_64-linux-gnu RANLIB="${QNX_BINS}/aarch64-unknown-nto-qnx7.0.0-ranlib" AR="${QNX_BINS}/aarch64-unknown-nto-qnx7.0.0-ar" LD="${QNX_BINS}/aarch64-unknown-nto-qnx7.0.0-ld" LDCXX="${QNX_BINS}/aarch64-unknown-nto-qnx7.0.0-ld"

I can't really offer any help here, since I'm not familiar with and don't have access to QNX. You might try installing the latest auto tools (autoconf, automake, libtool) on your QNX system and re-generate the configure script on the system (by running aclocal, acheader, autoconf, etc.), and see if that resolves it.

hi, cy did fix this issue? cus im facing the same issue.

[cy-goh]

@zangetsudo nope, I didn't get it to work. In the end I used another header only library.

I have succeeded in building libconfig for qnx7 aarch64le in windows by using msys2.
The tricky part was adding -Vgcc_ntoaarch64le to CC and CXX.

Please use the following example:

export QNX_HOST=/c/QNX/qnx710/host/win64/x86_64 #Please change the qnx path
export QNX_TARGET=/c/QNX/qnx710/target/qnx7 #Please change the qnx path
export SYSROOT=$QNX_TARGET/aarch64le/usr/
export ABI=aarch64-unknown-nto-qnx7.1.0

export AR=$QNX_HOST/usr/bin/$ABI-ar.exe
export AS=$QNX_HOST/usr/bin/$ABI-as.exe
export CC="$QNX_HOST/usr/bin/qcc.exe -Vgcc_ntoaarch64le"
export CXX="$QNX_HOST/usr/bin/q++.exe -Vgcc_ntoaarch64le_gpp"
export LD=$QNX_HOST/usr/bin/$ABI-ld.exe
export NM=$QNX_HOST/usr/bin/$ABI-nm.exe
export OBJDUMP=$QNX_HOST/usr/bin/$ABI-objdump.exe
export RANLIB=$QNX_HOST/usr/bin/$ABI-ranlib.exe
export STRIP=$QNX_HOST/usr/bin/$ABI-strip.exe
export CFLAGS="-fPIC -D_QNX_SOURCE -O3"
export CXXFLAGS="-stdlib=libstdc++ -fPIC -D_QNX_SOURCE -O3"
export LDFLAGS="-pie"

mkdir -p out
export OUTDIR=$PWD/out

autoreconf -if
./configure --prefix=$OUTDIR --host=$ABI --with-sysroot=$SYSROOT --enable-static=no --disable-cxx --disable-doc --disable-examples
make clean
make AM_DEFAULT_VERBOSITY=1 -j16
make install
