I am having this strange issue with building a library and then linking it to
an executable.
If I have the following in my CMakeList:
add_library(libfoo.a ${srcfiles})
add_executable(foo_exec.Fx foo_exec.F)
target_link_libraries(foo_exec.Fx libfoo.a)
I get an error returned of "no rule to make target libfoo.a needed by
foo_exec.Fx."
I should mention I have library prefixes and suffixes turned off for both
linking and building, meaning that the full filename of libraries are specified
(hence the libfoo.a and not just foo).
But if I change my CMakeList to:
add_library(libfoo.a ${srcfiles})
#add_executable(foo_exec.Fx foo_exec.F)
#target_link_libraries(foo_exec.Fx libfoo.a)
It builds libfoo.a without any complaint. When I uncomment the executable
lines after building libfoo.a via the above, the library is linked to the
executable with no complaints.
I might also mention since the Fortran compiler used is ABSoft and I am
building on a 64-bit Redhat system, the linker I am using for Fortran
executables is g++, but that may be irrelevant.
How do I specify that the library needs to be built before the executable which
links to it, so that CMake does not return an error when it tries to build and
link the executable before building its dependent library?
This almost seems like a bug in CMake.
