NSAssert and noescape?

[Aaron Hillegass]

Hi,

I’m porting the FMDB library to run on GNUstep on Linux:

https://github.com/ccgus/fmdb

I’m getting errors with the vargs on NSAssert:
FMDatabase.m:1495:36: error: too many arguments provided to function-like macro invocation
            NSAssert(false, @"%@", [self lastErrorMessage]);
                                   ^
/usr/local/include/Foundation/NSException.h:475:9: note: macro 'NSAssert' defined here
#define NSAssert(condition, desc)                      

I’m also getting some warnings on noescape:
./FMDatabasePool.h:199:36: warning: unknown attribute 'noescape' ignored [-Wunknown-attributes]
- (void)inDatabase:(__attribute__((noescape)) void (^)(FMDatabase *db))block;

I’d appreciate any help I can get.

P.S.

Trivia for other who will come after me: I had to install libbsd and libdispatch. As a dumb work-around, I also defined some empty macros:

#ifdef __linux__
    #define SInt32 int32_t
    #define NS_SWIFT_NAME(the_name)
    #define __deprecated_msg(the_message)
#endif

Here’s how I’m building it:

clang -x objective-c -fconstant-string-class=NSConstantString -fPIC -fobjc-nonfragile-abi -fblocks  -I/usr/local/include/ -c FMDatabase.m -o FMDatabase.o
