fix compilation error when building Ghostscript 9.53.3 on top of freetype 2.10.3: error: expected declaration specifiers before FF_alloc see also https://bugs.ghostscript.com/show_bug.cgi?id=702985 From 41ef9a0bc36b9db7115fbe9623f989bfb47bbade Mon Sep 17 00:00:00 2001 From: Chris Liddell Date: Tue, 20 Oct 2020 09:49:45 +0100 Subject: [PATCH] Bug 702985: drop use of FT_CALLBACK_DEF() def From 2.10.3, Freetype disappeared the FT_CALLBACK_DEF() macro, which is what we used when defining our callbacks from Freetype. No guidance forthcoming from the Freetype developer who made those changes, so change to explicitly declaring the callbacks file static. Should fix the reported build failures. --- base/fapi_ft.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/base/fapi_ft.c b/base/fapi_ft.c index 65fa6dcf4..21aef2f06 100644 --- a/base/fapi_ft.c +++ b/base/fapi_ft.c @@ -125,7 +125,7 @@ static void delete_inc_int_info(gs_fapi_server * a_server, FT_IncrementalRec * a_inc_int_info); -FT_CALLBACK_DEF(void *) +static void * FF_alloc(FT_Memory memory, long size) { gs_memory_t *mem = (gs_memory_t *) memory->user; @@ -133,7 +133,7 @@ FF_alloc(FT_Memory memory, long size) return (gs_malloc(mem, size, 1, "FF_alloc")); } -FT_CALLBACK_DEF(void *) +static void * FF_realloc(FT_Memory memory, long cur_size, long new_size, void *block) { gs_memory_t *mem = (gs_memory_t *) memory->user; @@ -153,7 +153,7 @@ FT_CALLBACK_DEF(void *) return (tmp); } -FT_CALLBACK_DEF(void) +static void FF_free(FT_Memory memory, void *block) { gs_memory_t *mem = (gs_memory_t *) memory->user; -- 2.17.1
