I have tried to install the sage package gap_packages as following

$ sage -v
SageMath version 9.2, Release Date: 2020-10-24
$ sage -i gap_packages

on macOS 10.15 (Catalina) returns

Building GAP package cohomolo-1.6.7

Error installing package gap_packages-4.10.2.p1
Please email sage-devel
explaining the problem and including the log file
Describe your computer, operating system, etc.
If you want to try to fix the problem yourself, *don't* just cd to
/Applications/SageMath/local/var/tmp/sage/build/gap_packages-4.10.2.p1 and type 'make' or whatever is appropriate.
Instead, the following commands setup all environment variables
correctly and load a subshell for you to debug the error:
  (cd '/Applications/SageMath/local/var/tmp/sage/build/gap_packages-4.10.2.p1' && '/Applications/SageMath/sage' --buildsh)
When you are done debugging, you can type "exit" to leave the subshell.

Compiler from XCode:

$ gcc --version
Configured with: --prefix=/Applications/ --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/include/c++/4.2.1
Apple clang version 12.0.0 (clang-1200.0.32.27)
Target: x86_64-apple-darwin19.6.0
Thread model: posix
InstalledDir: /Applications/

The error can be disabled with the compiler flag -Wno-implicit-function-declaration.

I could proceed with the compilation as following by editing manually the Makefile with vim

$ (cd '/Applications/SageMath/local/var/tmp/sage/build/gap_packages-4.10.2.p1' && '/Applications/SageMath/sage' --buildsh)
$ cd src/pkg/cohomolo-1.6.7/
$ vim Makefile

I have modified the rule all to following:

    mkdir -p bin/x86_64-apple-darwin19.6.0-default64-kv3;
    cd standalone/progs.d;\
    $(MAKE) CC="$(CC) -Wno-implicit-function-declaration" BIN="..//..//$(BIN)" COPTS="$(COPTS)"

Now at least I can run make

 $ pwd
 $ make

How can I finish the installation of gap_packages from this subshell?

If you are willing to build Sage from source, I believe that version 9.3.beta1 has a fix to allow gap_packagesto build with the latest version of Xcode. (See, which should be included in the latest beta versions.)

You can also apply the changes at directly to your current version of Sage. They should allow gap_packages to build.

Workaround: Disable gap packages with build issues

If you do not need the gap packages

  • cohomolo-*
  • crypting-*
  • grape-*
  • guava-*
  • orb-*

comment them in the spkg-install script for the sage package gap_packages.

$ sage -i gap_packages
... error message ...
$ (cd '/Applications/SageMath/local/var/tmp/sage/build/gap_packages-4.10.2.p1' && '/Applications/SageMath/sage' --buildsh)
$ vim spkg-install

and comment gap packages with build issues:

 96 # Build and install compiled packages:
 97 #
 98 # These packages have an old ./configure that take the GAP_ROOT as a positional
 99 # argument
100 # for pkg in cohomolo-* crypting-* grape-* guava-* orb-*
101 # do
102 #     echo "Building GAP package $pkg"
103 #     cd "$PKG_SRC_DIR/$pkg"
104 #     ./configure "$GAP_ROOT"
105 #     sdh_make -j1
106 #     install_compiled_pkg "$pkg"
107 #     cd "$PKG_SRC_DIR"
108 # done

and then proceed within the subshell with the compilation and installation with

$ ./spkg-install
