Sorry about that. I imported it as is, so I will change to 0pl with
EPOCH. Here is an inline diff that does the following:
- bump EPOCH because version is erroneously marked 1.0. start with 0pl
in order to leave room for future release names.
- update to 0pl20230220
- major bump chdr because long --> long long in function signature
while here:
- add devel category
- build with system zlib and add z to WANTLIB
- add license marker for lzma and zlib
details on major bump:
check_sym doesn't reveal much.
/usr/local/lib/libchdr.so.0.0 --> /usr/local/lib/libchdr.so.1.0
No dynamic export changes
External reference changes:
added:
inflate
inflateEnd
inflateInit2_
inflateReset
However, diffing headers
(https://namtsui.com/public/chdr_major_bump.txt) reveals that long was
changed to INT64 aka long long. Types changed in an incompatible way in
a public header (coretypes.h), so a major bump is warranted.
- int (*fseek)(struct chd_core_file*, long, int);
+ int (*fseek)(struct chd_core_file*, INT64, int);
-static inline int core_fseek(core_file* fp, long offset, int whence) {
+static inline int core_fseek(core_file* fp, INT64 offset, int whence) {
emulators/flycast still compiles.
OK?
