Hi,
I’m writing a C extension and have successfully based my Makefile on existing templates. This conveniently hides the
detailsof the full Makefile provided by "pg_config --pgxs”. Which variable would be the appropriate one to specify the
‘-std=c99’compiler flag? I’ve tried many and still get warnings that this flag should suppress (specifically, "ISO C90
forbidsmixed declarations and code”). These are the variables I currently define:
EXTENSION
DATA
PGFILEDESC
MODULE_big
PG_CPPFLAGS (this one seemed like the right place)
SHLIB_LINK
OBJS
PG_CONFIG
PGXS
A workaround has been:
OBJS = file1.o file2.o CPPFLAGS+=-Wdeclaration-after-statement
but it’s not exactly the same thing.
Thanks,
Demitri
