LAPACK/ScaLAPACK Development

So I would like to build a shared library of clapack through cmake. What is the prcedure?

When I put SET(BUILD_SHARED_LIBS ON) to CMakeLists.txt i run cmake . and then make, I get an error
.....
[ 5%] Building C object F2CLIBS/libf2c/CMakeFiles/f2c.dir/etime_.c.o
Linking C shared library libf2c.dylib
Undefined symbols:
"_MAIN__", referenced from:
_main in main.c.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
make[2]: *** [F2CLIBS/libf2c/libf2c.dylib] Error 1
make[1]: *** [F2CLIBS/libf2c/CMakeFiles/f2c.dir/all] Error 2
make: *** [all] Error 2

I run it on osx snow leopard and I have installed gfortran and f2c from http://www.webmo.net/support/fortran_osx.html

Any ideas?

Best Regards,

i found a sort of solution for mac osx
adding this to CMakeLists.txt
IF(APPLE)
set(CMAKE_SHARED_LINKER_FLAGS "-undefined dynamic_lookup")
ENDIF(APPLE)

I don't know if it is ok or not

What do you think?

Also if somehow setting a command line option with -DVARIABLE:TYPE=VALUE could set the
SET(BUILD_SHARED_LIBS ON)
and then some if-else checking this variable and customizing depending on platform (as above)

georgiuk,

Looking over this code, that should work. Have you tried it out and if so, what results did you get back?
There is a cli option with the DVARIABLE:TYPE=VALUE but i don't have the syntax off hand.
