OK, I've built a system from source, specifically 64 Bit with a view to building a fully native 64 bit program (binaries exist, but they depend on ia32).

I've hit a snag with hacd library. I haved the source, and it's built without problems. I've copied the headers to /usr/include, and they are found OK. However, hacd library is giving me some problems. The build produces a /bin/libHACD.a, but no .so. (Maybe HACDLib - I forget the precise name and I'm not on the dev system ATM)

Does anyone have any idea whatsoever how I get a working .so from this?

The target build uses cmake, and I've built boost-cmake which is now found. I suspect that boost interacts with hacd somehow, but I'm getting lost.

Just a clue would be nice. HACD docs leave a lot to be desired.

Example, 32bits :
cd hacd/src/ && mkdir build_shared && cd build_shared/
&& cmake CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fPIC -std=c99" ../
&& make
&& cd HACD_Lib/CMakeFiles/HACD_LIB.dir/src/ &&
gcc -shared -Wl,-soname,libHACD.so -o libHACD.so *.o -lc

( Or : gcc -shared -Wl,-soname,libHACD.so.1 -o libHACD.so.1.0 *.o -lc ).


The 'file' command reports this ..

P.S. : No luck so far with the above on a 64bits OS.

..

Closer than I got, but still no joy with 64 bit here, either. I can start to look over the output tomorrow to try to debug, though. Looks like it's failing on some math here, but I need to look closer.

Simpler than I thought. "HACD_Lib" is a very small application,
159 kB .cpp files, and 88.3 kB headers (inc/).
And uncomplicated : One .cpp file for each object.

("The other 250 MB" in the hacd package is data.)


cd hacd/src/HACD_Lib/src/
g++ -fPIC -g -c -Wall -I../inc *.cpp
gcc -shared -Wl,-soname,libHACD.so -o libHACD.so *.o -lc


The 64bits Slackware 13.1 was used for the test. (g++-4.4.4).
$file libHACD.so :
libHACD.so: ELF 64-bit LSB shared object, x86-64,
version 1 (SYSV), dynamically linked, not stripped

I hope the created libHACD.so will work as expected.

Regards.
