-l flags wrongly ordered
|Assignee:||Hiroyuki Yamamoto||% Done:|
I maintain the sylpheed package for the Fink packaging system for OS X. A Fink developer reported that sypheed fails to build if avfs-dev is installed. Terminal output:

[skipping some warnings that aren't relevant to this bug]
folderview.c: In function 'folderview_rename_folder_cb':

folderview.c: In function 'folderview_delete_folder_cb':
folderview.c:2723: error: invalid type argument of '->'
Happens when avfs-dev is installed, because that package supplies /sw/include/virtual.h but when folderview.c says '#include "plugin.h" it wants the one that is part of the sources being built, not some external library's. The bug is in the ordering of the -I flags: notice that some of the /sw ones come before ../libsylph rather than the universally proper "all local -I before any external/global ones" way.
#1 Updated by Daniel Macks almost 4 years ago
(the fink developer, following up)
I misreported the .h to Kevin--it's actually #include "virtual.h"' that leads to the misloading (not sure if plugin.h was part of some #include spaghetti or I just copied that line from the wrong source file).
I see the same flag ordering situation in the INCLUDES of several different Makefile.am (tested on sylpheed-3.1.0 and the makefile templates look the same in the newer stable release version). Moving things like -I$(top_srcdir) -I$(top_srcdir)/src and -I$(top_srcdir)/libsylph to the beginning of that variable fixed the problem for me.
