How to configure to link with static option

[jlconlin]

If I invoke CMake with this command:

make -D static_libraries=True -D static_njoy=True../

then I don't get statically linked libraries as I would think. The command ldd (otool -L on Mac) lists the libraries that are statically linked and includes (on Linux gcc 6.3):

linux-vdso.so.1 =>  (0x00007ffc8ddfd000)
libgfortran.so.3 => /opt/local/packages/gcc/6.3.0/lib64/libgfortran.so.3 (0x00007fc9f68b9000)
libm.so.6 => /lib64/libm.so.6 (0x000000305f800000)
libgcc_s.so.1 => /opt/local/packages/gcc/6.3.0/lib64/libgcc_s.so.1 (0x00007fc9f667c000)
libquadmath.so.0 => /opt/local/packages/gcc/6.3.0/lib64/libquadmath.so.0 (0x00007fc9f643d000)
libc.so.6 => /lib64/libc.so.6 (0x000000305f400000)
/lib64/ld-linux-x86-64.so.2 (0x000000305f000000)

On my Mac (gcc 7.2) I get:

njoy:
  /usr/local/opt/gcc/lib/gcc/7/libgfortran.4.dylib (compatibility version 5.0.0, current version 5.0.0)
  /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.0.0)
  /usr/local/lib/gcc/7/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)
  /usr/local/opt/gcc/lib/gcc/7/libquadmath.0.dylib (compatibility version 1.0.0, current version 1.0.0)

You probably need to add -static-libgfortran and -static-libgcc on the link line. Don't know if you can get libquadmath statically linked though.

[whaeck]

You actually need to use an additional CMAKE flag to add "-static" to the linker flags:

-D CMAKE_EXE_LINKER_FLAGS="-static"

I had to do this when I was compiling njoy at IRSN.

@whaeck this seems to do the trick—at least on Linux. On my Mac, I get:

$ cmake -D static_libraries=TRUE -D CMAKE_EXE_LINKER_FLAGS="-static" ../

I have a similar problem on my linux. I will try adjust the LD_LIBRARY_PATH to see if that fixes it. I will update as required.

I just tried the following on snow and it allows me to build a static executable (i.e. ldd njoy will tell me that it is not a dynamic executable): cmake -Dstatic_libraries=ON -Dstatic_njoy=ON -DCMAKE_EXE_LINKER_FLAGS=-static ../
