Issue #20500 has been updated by lish82 (Hiroki Katagiri).
Or use `RUBY_CHECK_HEADER` instead of `AC_CHECK_HEADER?`
I think it's enough to solve the first problem (`Non-system directories are not searched when checking jemalloc headers`) But the process that checks `jemalloc` has a process that checks about library (I'm sorry but I don't know its details), which expects jemalloc headers to be included in the search path. So I think that just `RUBY_CHECK_HEADER` might not solve the second problem (Non-system directories are not searched when checking jemalloc libs) ---------------------------------------- Bug #20500: Non-system directories are not searched when checking for jemalloc headers and libs, and building `enc` https://bugs.ruby-lang.org/issues/20500#change-108386 * Author: lish82 (Hiroki Katagiri) * Status: Open * Assignee: nobu (Nobuyoshi Nakada) * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- I found a problem similar to #20494 on jemalloc It's similar to #20494, but it has a few more issues Problems: - Non-system directories (specified by `--with-opt-dir`) are not searched when checking jemalloc headers (almost the same as #20494) - Non-system directories are not searched when checking jemalloc libs - Non-system directories are not searched when building the `enc` directory sources I have confirmed that this problem can be fixed by applying the following patch: ```patch diff --git a/configure.ac b/configure.ac index 169662c..b2dce70 100644 --- a/configure.ac +++ b/configure.ac @@ -1392,6 +1392,8 @@ AC_ARG_WITH([jemalloc], [with_jemalloc=$withval], [with_jemalloc=no]) AS_IF([test "x$with_jemalloc" != xno],[ # find jemalloc header first + save_CPPFLAGS="${CPPFLAGS}" + CPPFLAGS="${INCFLAGS} ${CPPFLAGS}" malloc_header= AC_CHECK_HEADER(jemalloc/jemalloc.h, [malloc_header=jemalloc/jemalloc.h], [ AC_CHECK_HEADER(jemalloc.h, [malloc_header=jemalloc.h]) @@ -1423,6 +1425,8 @@ AS_IF([test "x$with_jemalloc" != xno],[ done done ]) + CPPFLAGS="${save_CPPFLAGS}" + unset save_CPPFLAGS with_jemalloc=${rb_cv_jemalloc_library} AS_CASE(["$with_jemalloc"], [no], diff --git a/enc/Makefile.in b/enc/Makefile.in index 6920bc9..ce93fdd 100644 --- a/enc/Makefile.in +++ b/enc/Makefile.in @@ -52,7 +52,7 @@ optflags = @optflags@ debugflags = @debugflags@ warnflags = @warnflags@ CCDLFLAGS = @CCDLFLAGS@ -INCFLAGS = -I. -I$(arch_hdrdir) -I$(hdrdir) -I$(top_srcdir) +INCFLAGS = -I. -I$(arch_hdrdir) -I$(hdrdir) -I$(top_srcdir) @incflags@ DEFS = @DEFS@ CPPFLAGS = @CPPFLAGS@ -DONIG_ENC_REGISTER=rb_enc_register LDFLAGS = @LDFLAGS@ ``` --- On a side note, I think there might be other parts affected by the changes bellow: https://github.com/ruby/ruby/pull/8449 I thought it might be a good idea to review everything thoroughly -- https://bugs.ruby-lang.org/
