Building Apache log4cxx with CMake - cmake

Question

I am trying build Apache log4cxx 0.13.0 for mingw in windows platform
I builder and installed apr and apr-util using MSYS2
I downloaded log4cxx source from apache repository
but when configuring with CMake it shows this error:
CMake Error at src/cmake/FindAPR.cmake:17 (message):
apr-1-config --includedir failed with result %1 is not a valid Win32
application
Call Stack (most recent call first):
src/cmake/FindAPR.cmake:35 (_apr_invoke)
CMakeLists.txt:44 (find_package)
CMakeOutput.log

Answer 1

apu-1-config of the apr-util package is actually a *nix shell script.
CMake is trying to run apr-1-config directly but of course Windows has no clue how to execute it.
The solution is execute sh.exe with apr-1-config (and its arguments) as argument(s).
The following patch fixes this issue for me:
patch -ulbf src/cmake/FindAPR.cmake << EOF
## -10,3 +10,3 ##
execute_process(
- COMMAND \${APR_CONFIG_EXECUTABLE} \${ARGN}
+ COMMAND sh \${APR_CONFIG_EXECUTABLE} \${ARGN}
OUTPUT_VARIABLE _apr_output
EOF
patch -ulbf src/cmake/FindAPR-Util.cmake << EOF
## -11,3 +11,3 ##
execute_process(
- COMMAND \${APR_UTIL_CONFIG_EXECUTABLE} \${ARGN}
+ COMMAND sh \${APR_UTIL_CONFIG_EXECUTABLE} \${ARGN}
OUTPUT_VARIABLE _apr_output
EOF
I have updated my winlibs build script (which is mostly MSYS2 shell commands) so it now builds the most recent Apache Log4cxx 0.13.0. Besides this issue I had to add a few more workarounds though...
