I am trying to build crash-9.0.0 on Ubuntu 24 LTS, but it always fails with below error : configure: error: Building GDB requires GMP 4.2+, and MPFR 3.1.0+. Try the --with-gmp and/or --with-mpfr options to specify $ pkg-config --modversion gmp 6.3.0 $ pkg-config --modversion mpfr 4.2.1 $ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 24.04.1 LTS Release: 24.04 Codename: noble The packages are properly installed and the header files are also present : $ ls /usr/include/x86_64-linux-gnu/gmp.h /usr/include/x86_64-linux-gnu/gmp.h $ ls /usr/include/mpfr.h /usr/include/mpfr.h I even tried this : $ CPPFLAGS="-I/usr/include/x86_64-linux-gnu -I/usr/include" LDFLAGS="-L/usr/lib/x86_64-linux-gnu" make target=ARM but still same error. Can someone please give any pointers. Regards, Naveen
