From: notaz Date: Thu, 12 Oct 2017 21:39:51 +0000 (+0300) Subject: re-import all libretro code from it's fork X-Git-Tag: v1.93~49 X-Git-Url: https://notaz.gp2x.de/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7612bf90bef4f54e60865db057040b62c289ea34;p=picodrive.git re-import all libretro code from it's fork Verbatim copy from https://github.com/libretro/picodrive/ commit 9ae88ef15ff00cacc3877c7ecc13b0092bab50b8 , so look there for the history of libretro specific changes. Unfortunately there is too much noise and divergence to merge this in a proper way. --- diff --git a/Makefile b/Makefile index ff008506..f0cd64ef 100644 --- a/Makefile +++ b/Makefile @@ -111,7 +111,7 @@ USE_FRONTEND = 1 PLATFORM_MP3 = 1 endif ifeq "$(PLATFORM)" "libretro" -OBJS += platform/libretro.o +OBJS += platform/libretro/libretro.o endif ifeq "$(USE_FRONTEND)" "1" @@ -181,7 +181,11 @@ clean: $(RM) -r .opk_data $(TARGET): $(OBJS) +ifeq ($(STATIC_LINKING), 1) + $(AR) rcs $@ $^ +else $(CC) -o $@ $(CFLAGS) $^ $(LDFLAGS) $(LDLIBS) +endif pprof: platform/linux/pprof.c $(CC) -O2 -ggdb -DPPROF -DPPROF_TOOL -I../../ -I. $^ -o $@ diff --git a/Makefile.libretro b/Makefile.libretro index 5d5f4729..14f2dc50 100644 --- a/Makefile.libretro +++ b/Makefile.libretro @@ -1,16 +1,20 @@ # Makefile for PicoDrive (libretro) ifeq ($(platform),) -platform = unix -ifeq ($(shell uname -a),) -
