If you downloaded an archive:\n\n```\n\u003e tar xzvf givaro-*.tar.gz\n\u003e cd givaro-*\n\u003e ./configure --prefix=##GIVAROROOT##\n\u003e make\n$ make install\n```\n\nIf you cloned the git repository directly, replace `./configure` by `./autogen.sh`:\n```\n\u003e git clone git@github.com:linbox-team/givaro.git\n\u003e cd givaro\n\u003e ./autogen.sh --prefix=##GIVAROROOT##\n\u003e make\n$ make install\n```\nRunning ./autogen.sh will create a configure file that can be used directly for later re-compilations.\n\n*Configuration can be adapted. Check `configure --help` to print the parameter choices.*\n\n*In particular if GMP is not installed to the default location you might need to add for instance `--with-gmp=##GMPROOT##/gmp-x-y-z` to the configure line.*\n\n*Also, on non-Linux systems you might need to use `gmake` instead of `make`.*\n\n## Compile your own files\n\nGivaro uses pkgconfig to expose the compilation flags it requires.\n\nYou will get the compilation flags by calling\n```\npkg-config --cflags givaro\n```\nand the linking flags by calling\n```\npkg-config --libs givaro\n```\n\nIf you have installed givaro in a non-standard directory (such as `/usr/local`), make sure to have added the path where to find givaro's .pc file to the PKG_CONFIG_PATH environment variable.\n```\nPKG_CONFIG_PATH=${PKG_CONFIG_PATH}:\u003cpath to your givaro install\u003e/lib/pkgconfig\n```\n\nAn alternative option is to just add the following line to your Makefile. Then a simple call will compile your C and C++ files.\n```\ninclude ##GIVAROROOT##/share/givaro/givaro-makefile\n```\n\n\n## Frequently Asked Questions\n\n- **When compiling, I get error messages similar to**\n```\n/tmp/ccjZqIED.s: Assembler messages:\n/tmp/ccjZqIED.s:142: Error: operand type mismatch for `vxorps'\n/tmp/ccjZqIED.s:768: Error: no such instruction: `shlx %rax,%rdx,%rdx'\n/tmp/ccjZqIED.s:1067: Error: no such instruction: `shlx %rax,%rdx,%rdx'\n```\n\n\nIt means that the assembler is not capable of handling instructions generated by\nthe compiler. You should either upgrade your assembler (e.g., by upgrading\nbinutils on Linux) or use **CXXFLAGS** in `./configure` to controls the\ninstructions generated by the compiler (e.g., by adding -march=..., or\n-mno-avx2 or similar, depending on your machine and assembler version).\n\nFor more information, see [this link](https://stackoverflow.com/a/51506666).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flinbox-team%2Fgivaro","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flinbox-team%2Fgivaro","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flinbox-team%2Fgivaro/lists"}
