From 5a053ffe80289b8472f88d7f11f29fbc98d4d9fd Mon Sep 17 00:00:00 2001 From: Yang Tse Date: Sun, 6 Jan 2013 19:06:49 +0100 Subject: build: fix circular header inclusion with other packages This commit renames lib/setup.h to lib/curl_setup.h and renames lib/setup_once.h to lib/curl_setup_once.h. Removes the need and usage of a header inclusion guard foreign to libcurl. [1] Removes the need and presence of an alarming notice we carried in old setup_once.h [2] ---------------------------------------- 1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H, this single inclusion guard is enough to ensure that inclusion of lib/setup_once.h done from lib/setup.h is only done once. Additionally lib/setup.h has always used __SETUP_ONCE_H macro to protect inclusion of setup_once.h even after commit ec691ca3, this was to avoid a circular header inclusion triggered when building a c-ares enabled version with c-ares sources available which also has a setup_once.h header. Commit ec691ca3 exposes the real nature of __SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard foreign to libcurl belonging to c-ares's setup_once.h The renaming this commit does, fixes the circular header inclusion, and as such removes the need and usage of a header inclusion guard foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl. 2 - Due to the circular interdependency of old lib/setup_once.h and the c-ares setup_once.h header, old file lib/setup_once.h has carried back from 2006 up to now days an alarming and prominent notice about the need of keeping libcurl's and c-ares's setup_once.h in sync. Given that this commit fixes the circular interdependency, the need and presence of mentioned notice is removed. All mentioned interdependencies come back from now old days when the c-ares project lived inside a curl subdirectory. This commit removes last traces of such fact. --- docs/examples/Makefile.am | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'docs/examples/Makefile.am') diff --git a/docs/examples/Makefile.am b/docs/examples/Makefile.am index 865f09371..cbfdac502 100644 --- a/docs/examples/Makefile.am +++ b/docs/examples/Makefile.am @@ -31,7 +31,7 @@ EXTRA_DIST = README Makefile.example Makefile.inc Makefile.m32 \ # might possibly already be installed in the system. # # $(top_builddir)/include/curl for generated curlbuild.h included from curl.h -# $(top_builddir)/include for generated curlbuild.h included from lib/setup.h +# $(top_builddir)/include for generated curlbuild.h inc. from lib/curl_setup.h # $(top_srcdir)/include is for libcurl's external include files AM_CPPFLAGS = -I$(top_builddir)/include/curl \ -- cgit v1.2.3
