Description
Looks like Gammalib doesn’t support out-of-source builds ... it falls over with the Python extensions:
https://gist.github.com/cdeil/804e727d7b5bd038f8ea
Out-of-source builds are important for developers that want to test multiple compilers / options, or have debug / production builds, switch between branches ... basically everyone that wants to have more than one build.
Possible?
Recurrence
No recurrence.

What are out of source builds?
#2
Updated by Deil Christoph almost 9 years ago
An in-source build is if the generated files (object files, library files ... any generated files) are mixed with the source files.
An out-of source build is if the generated files go to a separate folder, leaving the source folder clean.

- Target version set to 1.1.0
The following should work:
make distclean mkdir build cd build ../configure --srcdir=.. make
For the moment it crashes with:
../../pyext/gammalib/app.i:43: Error: Unable to find 'typemap_GFilename.i' ../../pyext/gammalib/model.i:43: Error: Unable to find 'typemap_GFilename.i' ../../pyext/gammalib/model.i:46: Error: Unable to find 'GBase.i' ../../pyext/gammalib/model.i:47: Error: Unable to find 'GContainer.i' ../../pyext/gammalib/model.i:48: Error: Unable to find 'GRegistry.i' ../../pyext/gammalib/model.i:51: Error: Unable to find 'GException.i' ...

The following works now:
make distclean mkdir build cd build ../configure --srcdir=.. make -j8 make check
however the following still fails:
./configure make dist make distcheck clang -fno-strict-aliasing -fno-common -dynamic -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I../../../include -I../../../inst/mwl/include -I../../../inst/cta/include -I../../../inst/lat/include -I../../../inst/com/include -I/usr/local/include -I/usr/local/opt/openssl/include -I/usr/local/opt/sqlite/include -I/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c gammalib/app_wrap.cpp -o build/temp.macosx-10.11-x86_64-2.7/gammalib/app_wrap.o clang: error: no such file or directory: 'gammalib/app_wrap.cpp' clang: error: no input files error: command 'clang' failed with exit status 1
and also the following
../configure make dist make distcheck Making all in pyext /Applications/Xcode.app/Contents/Developer/usr/bin/make all-am make[4]: *** No rule to make target `../test/test_python.py', needed by `all-am'. Stop.
#5
Updated by Knödlseder Jürgen almost 8 years ago
The second problem was solved by adding the .py files to EXTRA_DIST in the test Makefile.am, now we have
../configure make dist make distcheck clang -fno-strict-aliasing -fno-common -dynamic -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I../../../include -I../../../inst/mwl/include -I../../../inst/cta/include -I../../../inst/lat/include -I../../../inst/com/include -I/usr/local/include -I/usr/local/opt/openssl/include -I/usr/local/opt/sqlite/include -I/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c gammalib/app_wrap.cpp -o build/temp.macosx-10.11-x86_64-2.7/gammalib/app_wrap.o clang: error: no such file or directory: 'gammalib/app_wrap.cpp' clang: error: no input files error: command 'clang' failed with exit status 1so the same error is for the build in the source directory.

This now works for Gammalib. Merged into devel. Still need to make sure that ctools also supports out of source builds.

- Status changed from In Progress to Closed
- % Done changed from 80 to 100
This now also works for ctools.
