For each configuration + there is one ".input" file and matching ".output" files in +ParseImplicitIncludeInfo/results and ParseImplicitLinkInfo/results. + +To generate ".input" files for a system, create a temporary build +directory and chdir to it. Then run cmake pointing to this directory. +The CMakeLists.txt file here will generate ".input" files in your +build directory. The default set of languages is C and CXX. This +can be changed with -DLANGUAGES=language_list. For example: +-DLANGUAGES=Fortran will generate Fortran parser input. + +The ".output" files should be generated by hand from the input files. +The test will compare the parser output to the manually generated +".output" file. The two should match. + +For compilers that support "-nostdinc"-like flags, you can generate +a test for this with a command like: +cmake -DUNAME=netbsd_nostdinc \ + -DCMAKE_C_FLAGS=-nostdinc -DCMAKE_CXX_FLAGS=-nostdinc . + +Here is an example for testing the XL compiler with both -I and nostdinc: + +env CC=xlc CXX=xlC cmake -DUNAME=linux_nostdinc_i \ + -DCMAKE_C_FLAGS='-qnostdinc -I/tmp/ii/test_c' \ + -DCMAKE_CXX_FLAGS='-qnostdinc -I/tmp/ii/test_c -I/tmp/ii/test_cxx' . |
