Without that, perl enables HAS_MEMRCHR during configure but later compiles op.c without a visible prototype and fails on an implicit declaration of memrchr.\n\nAlso add a Buildroot patch for ext/re/re_top.h to rename additional regex helper symbols in static builds. This avoids duplicate symbol errors when both libperl.a and lib/auto/re/re.a export the same Perl_* regex helpers while linking the final static perl binary.\n\nSigned-off-by: Shubham Chakraborty \n---\n ...name-additional-static-regex-symbols.patch | 35 +++++++++++++++++++\n package/perl/perl.mk | 10 +++++-\n 2 files changed, 44 insertions(+), 1 deletion(-)\n create mode 100644 package/perl/0001-ext-re-rename-additional-static-regex-symbols.patch","diff":"diff --git a/package/perl/0001-ext-re-rename-additional-static-regex-symbols.patch b/package/perl/0001-ext-re-rename-additional-static-regex-symbols.patch\nnew file mode 100644\nindex 0000000000..1dc4c708e6\n--- /dev/null\n+++ b/package/perl/0001-ext-re-rename-additional-static-regex-symbols.patch\n@@ -0,0 +1,35 @@\n+From 45895a24147d1fd8d07abfe83f5b0013138f018a Mon Sep 17 00:00:00 2001\n+From: Shubham Chakraborty \n+Date: Fri, 3 Apr 2026 13:41:15 +0530\n+Subject: [PATCH] ext/re: rename additional static regex symbols\n+\n+---\n+ ext/re/re_top.h | 12 ++++++++++++\n+ 1 file changed, 12 insertions(+)\n+\n+diff --git a/ext/re/re_top.h b/ext/re/re_top.h\n+index 4766b10..8c6d755 100644\n+--- a/ext/re/re_top.h\n++++ b/ext/re/re_top.h\n+@@ -30,6 +30,18 @@\n+ #define Perl_reg_named_buff_scalar my_reg_named_buff_scalar \n+ #define Perl_reg_named_buff_all my_reg_named_buff_all \n+ #define Perl_reg_qr_package my_reg_qr_package\n++#define Perl_reg_add_data my_reg_add_data\n++#define Perl_release_RExC_state my_release_RExC_state\n++#define Perl_populate_anyof_bitmap_from_invlist \\\n++ my_populate_anyof_bitmap_from_invlist\n++#define Perl_populate_bitmap_from_invlist \\\n++ my_populate_bitmap_from_invlist\n++#define Perl_populate_invlist_from_bitmap \\\n++ my_populate_invlist_from_bitmap\n++#define Perl_add_above_Latin1_folds my_add_above_Latin1_folds\n++#define Perl_set_ANYOF_arg my_set_ANYOF_arg\n++#define Perl_get_ANYOFM_contents my_get_ANYOFM_contents\n++#define Perl_get_ANYOFHbbm_contents my_get_ANYOFHbbm_contents\n+ \n+ /* We override these names because currently under static builds\n+ * we end up with confusion between the normal regex engine and\n+-- \n+2.53.0\n+\ndiff --git a/package/perl/perl.mk b/package/perl/perl.mk\nindex c96eb44135..8bfc829d9a 100644\n--- a/package/perl/perl.mk\n+++ b/package/perl/perl.mk\n@@ -45,6 +45,14 @@ ifeq ($(BR2_PACKAGE_GDBM),y)\n PERL_DEPENDENCIES += gdbm\n endif\n \n+PERL_CFLAGS = $(TARGET_CFLAGS)\n+\n+# perl-cross detects memrchr() with _GNU_SOURCE enabled, but the actual perl\n+# build does not inherit that on musl unless we add it explicitly.\n+ifeq ($(BR2_TOOLCHAIN_USES_MUSL),y)\n+PERL_CFLAGS += -D_GNU_SOURCE\n+endif\n+\n # We have to override LD, because an external multilib toolchain ld is not\n # wrapped to provide the required sysroot options.\n PERL_CONF_OPTS = \\\n@@ -52,7 +60,7 @@ PERL_CONF_OPTS = \\\n \t--target-tools-prefix=$(TARGET_CROSS) \\\n \t--prefix=/usr \\\n \t-Dld=\"$(TARGET_CC)\" \\\n-\t-Dccflags=\"$(TARGET_CFLAGS)\" \\\n+\t-Dccflags=\"$(PERL_CFLAGS)\" \\\n \t-Dldflags=\"$(TARGET_LDFLAGS) -lm $(TARGET_NLS_LIBS)\" \\\n \t-Dmydomain=\"\" \\\n \t-Dmyhostname=\"noname\" \\\n","prefixes":[]}
