| This directory contains sample input files for the implicit include |
| directories, and link info parsers for testing. 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' . |
