Hi, I’m trying to test libtiff on Cygwin, and I’m running into a failure. It’s finding and linking on all platforms with the exception of Cygwin (including MinGW64 and MSVC). For example:
https://gitlab.com/libtiff/libtiff/-/pipelines/2236584193 -- Found ZLIB: /usr/lib/libz.dll.a (found version "1.3.1") -- Found Deflate: /usr/lib/libdeflate.dll.a (found version "1.25") CMake Error at /usr/lib/cmake/libjpeg-turbo/libjpeg-turboTargets.cmake:99 (message): The imported target "libjpeg-turbo::jpeg" references the file "/usr/lib/libjpeg.dll.a" but this file does not exist. Possible reasons include: * The file was deleted, renamed, or moved to another location. * An install or uninstall procedure did not complete successfully. * The installation package was faulty and contained "/usr/lib/cmake/libjpeg-turbo/libjpeg-turboTargets.cmake" but not all the files it references. Call Stack (most recent call first): /usr/lib/cmake/libjpeg-turbo/libjpeg-turboConfig.cmake:37 (include) cmake/JPEGCodec.cmake:36 (find_package) It is entirely correct. The file that’s mentioned in the installed CMake config file does not exist. $ find lib -name '*jpeg*' lib/cmake/libjpeg-turbo lib/cmake/libjpeg-turbo/libjpeg-turboConfig.cmake lib/cmake/libjpeg-turbo/libjpeg-turboConfigVersion.cmake lib/cmake/libjpeg-turbo/libjpeg-turboTargets-relwithdebinfo.cmake lib/cmake/libjpeg-turbo/libjpeg-turboTargets.cmake lib/gdk-pixbuf-2.0/2.10.0/loaders/cygpixbufloader-jpeg.dll lib/libopenjpeg.dll.a lib/libturbojpeg.dll.a lib/openjpeg-1.5 lib/pkgconfig/libopenjpeg.pc lib/pkgconfig/libopenjpeg1.pc lib/pkgconfig/libturbojpeg.pc $ find bin -name '*jpeg*' bin/cygjpeg-8.dll bin/cygopenjpeg-1.dll bin/cygturbojpeg-0.dll So the DLL exists, but the import library does not. Everything else is present and correct as far as I can tell, but something is not right here. The import library is missing. $ grep '\.a' lib/cmake/libjpeg-turbo/* lib/cmake/libjpeg-turbo/libjpeg-turboTargets-relwithdebinfo.cmake: IMPORTED_IMPLIB_RELWITHDEBINFO "${_IMPORT_PREFIX}/lib/libjpeg.dll.a" lib/cmake/libjpeg-turbo/libjpeg-turboTargets-relwithdebinfo.cmake:list(APPEND _cmake_import_check_files_for_libjpeg-turbo::jpeg "${_IMPORT_PREFIX}/lib/libjpeg.dll.a" "${_IMPORT_PREFIX}/bin/cygjpeg-8.dll" ) lib/cmake/libjpeg-turbo/libjpeg-turboTargets-relwithdebinfo.cmake: IMPORTED_IMPLIB_RELWITHDEBINFO "${_IMPORT_PREFIX}/lib/libturbojpeg.dll.a" lib/cmake/libjpeg-turbo/libjpeg-turboTargets-relwithdebinfo.cmake:list(APPEND _cmake_import_check_files_for_libjpeg-turbo::turbojpeg "${_IMPORT_PREFIX}/lib/libturbojpeg.dll.a" "${_IMPORT_PREFIX}/bin/cygturbojpeg-0.dll" ) Because it’s referenced in the configuration, and has the DLL, and everything but this file is installed, this looks like a packaging error hence reporting it here as a bug.
