configure.ac: use pkg-config to find proj dependency #24
Conversation
Use pkg-config to retrieve proj and its static dependencies such as -lstdc++ Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com>

What is the behaviour with this commit if pkg-config itself is not found ? |
|
I assume that PKG_CHECK_MODULES will return PROJ_FOUND=no and current behavior will be used as fallback. A call to PKG_PROG_PKG_CONFIG could be added but PKG_CHECK_MODULES is already used for discovering tiff. However, this PR is useful only if OSGeo/PROJ#1664 is also merged. As stated in the other PR, the other available option, on buildroot side, is to disable libgeotiff for static builds. |
yes, but as a fallback. Would you mind testing your pull request by temporarily renaming the pkg-config binary ? |
|
OK, I finally found some time to test my PR with pkg-config binary renamed into "pkg-config-save". In this case, pkg-config is not found (as expected) and proj is found through the current mechanism (through AC_CHECK_LIB). |
