CMake improvements
by Alexey Sheplyakov 14 Oct '20

14 Oct '20

Hi! The patchset at https://github.com/asheplyakov/ginac/tree/cmake (git pull git://github.com/asheplyakov/ginac.git cmake) makes it a bit easier to build and use GiNaC with CMake. In particular 1) one can build both GiNaC and CLN in one pass (without having to make install, figure out CFLAGS, LD_LIBRARY_PATH, etc): git clone -b cmake git://github.com/asheplyakov/ginac.git cd ginac git clone -b cmake git://github.com/asheplyakov/cln.git mkdir build && cd build cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo .. make -j4 2) GiNaC can be included as CMake subproject: That is, to compile a program `derivative.cpp` (which uses GiNaC) one can download GiNaC sources into the `ginac` subdirectory (and CLN into ginac/cln subdirectory), and use the following CMakeLists.txt project(derivative) add_subdirectory(ginac) add_executable(derivative derivative.cpp) target_link_libraries(derivative ginac::ginac) # this adds both libraries and includes/defines 3) Targets are exported, so `find_package(ginac REQUIRED 1.7.0)` works "out of the box" (this requires CMake'ified CLN) Best regards, Alexey

Note: this works with GNU linker only. commit 7704505fbf7d969ff918f8bf2ff9ed976194987a Author: Alexey Sheplyakov <asheplyakov(a)altlinux.org> Date: Fri Dec 27 17:34:05 2019 +0400 build: CMake: made it easier to run tests in parallel As of now `make -jN check` executes test suite sequentially (although it builds test executables in parallel). This takes a bit too long, so it would be nice to run tests in parallel. `ctest -jN` or `make test ARGS=-jN` runs tests concurrently, however it does not build test executables, instead it fails if any test binary is missing. Also `test` target is a bit special and it's impossible to add dependencies to it, see https://gitlab.kitware.com/cmake/cmake/issues/8438 To work around the problem define `test_suite` target which builds the tests suite without running it, so one can both compile and run tests in parallel make -j8 test_suite make test ARGS=-j8 commit 51de097fb10f6167affe710328555113d7bcfa63 Author: Alexey Sheplyakov <asheplyakov(a)altlinux.org> Date: Wed Dec 25 20:41:17 2019 +0400 Made it easier to run tests on windows Put executables and DLLs into the `bin` subdirectory so the system can locate GiNaC (and CLN) DLLs without extra configuration. commit 08c190937df7e802393b588d3cc82d2bdf00b128 Author: Alexey Sheplyakov <asheplyakov(a)altlinux.org> Date: Wed Dec 18 16:39:12 2019 +0400 numeric.cpp, archive.cpp: don't include config.h config.h is necessary for excompiler only, the rest of the library is pretty portable.

CLN + CMake (yet another attempt)
by Alexey Sheplyakov 23 Aug '20

23 Aug '20

Hello! Here is a patchset which makes it possible to build CLN with CMake: https://github.com/asheplyakov/cln/tree/cmake (git pull git://github.com/asheplyakov/cln.git cmake) Best regards, Alexey P.S. I've sent this email several times to cln-devel@ (in December 2019, March 2020, etc), and it has been blocked by mailing list software. Hopefully ginac-devel is less strict.

Linking errors when building GiNaC
