Question

我正在安装一个库，并在make之后收到错误消息：

gcc -Wcast-qual -Wswitch -Werror-implicit-function-declaration -Wall -Wextra -Wundef -Wbad-function-cast -Wcast-align -Wstrict-prototypes -Wno-unused -std=c99  -U__STRICT_ANSI__ -g -O0 -UNDEBUG -I../mlgmpidl -I../apron -I/usr/include -I/usr/local/include -I/usr/lib/ocaml -I/usr/local/lib/ocaml -c -o scalar_caml_debug.o scalar_caml.c
In file included from scalar_caml.c:23:0:

make[1]: *** [scalar_caml_debug.o] Error 1

有谁知道发生了什么？也许它与GMP的版本有关，有谁知道如何检查它？非常感谢你

编辑1： ldconfig -p | grep gmp返回

libgmpxx.so.4 (libc6) => /usr/lib/libgmpxx.so.4
libgmpxx.so (libc6) => /usr/lib/libgmpxx.so
libgmp.so.3 (libc6) => /usr/lib/libgmp.so.3
libgmp.so (libc6) => /usr/lib/libgmp.so

/usr/local/include/包含：gmp.h mpf2mpfr.h mpfr.h，/usr/local/lib/包含 alt-ergo libgmp.a libgmp.so libgmp.so.10.0.2 libmpfr.la libmpfr.so.4 ocaml python2.7 coq libgmp.la libgmp.so.10 libmpfr.a libmpfr.so libmpfr.so.4.0.1 python2.6 site_ruby

有谁能告诉我我的机器上安装了哪个版本的GMP？

Answer 1

您的libgmp-dev版本可能比您使用的mlgmpidl版本旧，这说明mlgmpidl会询问未定义的内容。

编译，GMP，Ocaml的错误消息
