The ./configure script is meant to detect if caml_alloc_initialized_string is present in the OCaml version you are using and only substitute it if it's not present. See: https://github.com/libguestfs/libguestfs/blob/master/m4/guestfs-ocaml.m4#L163 What is the output of ./configure? > Can I disable ocaml when compile of libguestfs-1.48.4? No, it's required to compile the daemon. Anyway it should easy to fix this if you look at what ./configure is doing. (In reply to Richard W.M.

Anyway it should easy to fix > this if you look at what ./configure is doing. It says using --disable-ocaml only disables the bindings and OCaml tools in operation manual. When using --disable-ocaml, the chek for existence of this function is never run. And caml_alloc_initialized_string function definition in pcre-c.c has same name with the function in /usr/lib64/ocaml/caml/alloc.h I found a post with the same question, but that libguestfs version is 1.46.0: https://bugs.gentoo.org/820053 Please check it. Should be fixed in: https://github.com/libguestfs/libguestfs/commit/adfaf25a12b97b18f8a22d96803cd0920bfd25f7 (development branch) https://github.com/libguestfs/libguestfs/commit/f162e47ecfee711f2c3bcc761de17e502fe7ab5e (stable branch) Note that OCaml is required for building libguestfs. The ./configure --disable-ocaml option only disables the bindings (which is pretty pointless IMHO, but it's there in case you want it). |
Description of problem: In my project, I disabled ocaml use flag, compile of libguestfs-1.48.4 fails with Error: static declaration of ‘caml_alloc_initialized_string’ follows non-static declaration This is the excerpt of the build log: ocamlfind mklib \ augeas.cmx libmlaugeas_a-augeas-c.o -cclib -laugeas -o mlaugeas make[2]: Leaving directory '/usr1/zhudan/DataEnableEngine/3rd/src/guestfs/libguestfs-1.48.4/bundled/ocaml-augeas' Making all in common/mlpcre make[2]: Entering directory '/usr1/zhudan/DataEnableEngine/3rd/src/guestfs/libguestfs-1.48.4/common/mlpcre' CC libmlpcre_a-pcre-c.o pcre-c.c:47:1: error: static declaration of ‘caml_alloc_initialized_string’ follows non-static declaration caml_alloc_initialized_string (mlsize_t len, const char *p) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from pcre-c.c:31:0: /usr/lib64/ocaml/caml/alloc.h:35:18: note: previous declaration of ‘caml_alloc_initialized_string’ was here CAMLextern value caml_alloc_initialized_string (mlsize_t len, const char *); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ make[2]: *** [Makefile:1024: libmlpcre_a-pcre-c.o] Error 1 make[2]: Leaving directory '/usr1/zhudan/DataEnableEngine/3rd/src/guestfs/libguestfs-1.48.4/common/mlpcre' make[1]: *** [Makefile:1086: all-recursive] Error 1 make[1]: Leaving directory '/usr1/zhudan/DataEnableEngine/3rd/src/guestfs/libguestfs-1.48.4' make: *** [Makefile:992: all] Error 2 Can I disable ocaml when compile of libguestfs-1.48.4?
