Hi,
In my extension I want to define some custom options for compiler.
I do it in the following way:
ifdef USE_DISK
CUSTOM_COPT += -DIMCS_DISK_SUPPORT
endif
So if I want to enable disk support, I am building my extension as
make USE_DISK=1 clean all install
and it normally works... unless Postgres is built with --enable-llvm.
In this case it tries to build llvm code using clang and is not using
CUSTOM_COPTS:
gcc -Wall -Wmissing-prototypes -Wpointer-arith
-Wdeclaration-after-statement -Werror=vla -Wendif-labels
-Wmissing-format-attribute -Wformat-security -fno-strict-aliasing
-fwrapv -fexcess-precision=standard -g -O3 -Wall -pthread
-DIMCS_DISK_SUPPORT -fPIC -I. -I. -I../../src/include -D_GNU_SOURCE -c
-o disk.o disk.c
vs.
/usr/bin/clang -Wno-ignored-attributes -fno-strict-aliasing -fwrapv -O2
-I. -I. -I../../src/include -D_GNU_SOURCE -flto=thin -emit-llvm -c -o
disk.bc disk.c
I wonder is there any way to pass custom compile options to clang?
Thanks in advance,
