Compiling epsilon on Fedora 26 #3

Closed vsht closed 6 years ago

vsht commented 6 years ago

Hi,

I tried to compile epsilon on Fedora Linux 26 (64-bit version) but faced some difficulties that I'm unable to resolve. GiNaC and CLN are installed, libFermat also compiled just fine. However, for epsilon when I run 

cmake -DCMAKE_INSTALL_PREFIX=/usr/local

all I get is 

-- Checking for module 'cln'
--   Found cln, version 1.3.4
-- found CLN [/usr/include/cln/version.h], version 1.3.4
-- Checking for module 'ginac'
--   Found ginac, version 1.7.2
ERRORheader version differs from the library one, please check your installation.

I tried to modify CMakeLists.txt by replacing

find_package(GiNaC 1.6.2 REQUIRED)

with 

find_package(GiNaC 1.6.2 REQUIRED HINTS "/usr/include/")

which changed the error output to

CMake Error at epsilon-prepare/CMakeLists.txt:11 (find_package):
  Could not find a package configuration file provided by "GiNaC" (requested
  version 1.6.2) with any of the following names:

    GiNaCConfig.cmake
    ginac-config.cmake

  Add the installation prefix of "GiNaC" to CMAKE_PREFIX_PATH or set
  "GiNaC_DIR" to a directory containing one of the above files.  If "GiNaC"
  provides a separate development package or SDK, be sure it has been
  installed.

-- Configuring incomplete, errors occurred!
See also "/media/Data/Projects/Other/epsilon/CMakeFiles/CMakeOutput.log".

Unfortunately, I don't know where to get the corresponding cmake files for GiNaC. Any help would be highly appreciated!

Hi Vladyslav,

there seems to be something wrong with your GiNaC installation.

The message ERRORheader version differs from the library one, please check your installation. indicates that the C++ compiler finds both a header file ginac.h and a library file (something like libginac.so) on your system but they belong to different GiNaC versions. Did you install multiple GiNaC versions on your system (maybe from the package manager AND from some source packages on www.ginac.de)? You can try to locate both the header file and the library file, then uninstall GiNaC (if you installed it with the package manager) and then check if the two files are really gone. If not, also remove these files from your system. Then try to reinstall GiNaC again. (I usually compile GiNaC myself from the source packages on www.ginac.de).

Cheers, Mario

Hi Mario,

thanks for your prompt reply. Actually I only installed ginac and ginac-devel from the official Fedora repository, no multiple versions etc.

Nevertheless, I removed everything and tried to follow your advice, i.e. downloaded GiNaC from the official site (ginac-1.7.2.tar.bz2) and compiled it in the standard way

./configure && make && make install

As I already wrote, I have a pretty standard Fedora installation, everything (compilers, libraries etc.) are from the official package repository, no multiple versions installed or self-compiled exras. This is why I thought that everything should somehow work out of the box.

Hi Vladyslav,

at least we have a different message now: ERRORpkg-config and version.h disagree, vs 1.7.2, please check your installation

The cmake module FindGiNaC.cmake uses pkg-config to locate ginac. Try running pkg-config --modversion ginac which should print 1.7.2 in your case. If not, pkg-config didn't find ginac.pc which should be installed at /usr/local/lib/pkgconfig. It might be that pkg-config only looks at /usr/lib/pkgconfig. If this is so, you can add /usr/local/lib/pkgconfig to the environment variable PKG_CONFIG_PATH. You could also try installing ginac into /usr/lib and /usr/include. This can be done with ./configure --prefix=/usr.

Cheers, Mario

vsht commented 6 years ago

Hi Mario,

many thanks, using

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
cmake -DCMAKE_INSTALL_PREFIX=/usr/local

did the trick and epsilon finally compiled. After that the binaries could not find libFermat.so and libginac.so.6, but that was easy to fix via

sudo ln -s /usr/local/lib/libFermat.so /lib64/libFermat.so 
sudo ln -s /usr/local/lib/libginac.so.6 /lib64/libginac.so.6

I tried epsilon.sh in the example directory and it finished successfully, so I assume that everything is now working as it should.

Thanks a lot for your help!

Cheers, Vladyslav

mprausa commented 6 years ago

Hi Vladyslav,

I am glad to hear that.

Still one remark: Instead of the symlinks, you can add /usr/local/lib permanently to the environment variables LD_LIBRARY_PATH and LIBRARY_PATH. I would recommend this if you are using /usr/local/lib more often.

Cheers, Mario

I had the same problem and I'm also using Fedora 26. Is GiNac package for Fedora 26 is broken?
