Hi, According to https://my.eng.utah.edu/~pajensen/ACM/Documentation/gmplib.org/gmpbench.html To run the benchmarks, you also need to compile gexpr.c and put it somewhere in your path.
I've downloaded https://gmplib.org/gexpr.c and got those warnings with gcc 15: gexpr.c:130:12: error: initialization of ‘double (*)(void)’ from incompatible pointer type ‘double (*)(double)’ [-Wincompatible-pointer-types] 130 | {"log2", my_log2}, | ^~~~~~~ gexpr.c:130:12: note: (near initialization for ‘fns[0].evalfn’) gexpr.c:123:1: note: ‘my_log2’ declared here 123 | my_log2 (double x) | ^~~~~~~ gexpr.c:131:13: error: initialization of ‘double (*)(void)’ from incompatible pointer type ‘double (*)(double)’ [-Wincompatible-pointer-types] 131 | {"log10", log10}, | ^~~~~ ... SNIP: multiple more for all functions in fns-array. Simply adjusting the function prototype silences those warnings: --- gexpr_orig.c 2025-06-24 09:40:21.747880242 +0200 +++ gexpr.c 2025-06-24 09:31:13.507903946 +0200 @@ -116,7 +116,7 @@ struct functions { char *spelling; - double (* evalfn) (); + double (* evalfn) (double); }; double Can you please adjust https://gmplib.org/gexpr.c?
