Hi Matthew,

typically you would pass this using the -std option

% gcc -dM -E - < /dev/null | grep STDC_VERSION

% gcc --std=c99 -dM -E - < /dev/null| grep STDC_VERSION
#define __STDC_VERSION__ 199901L

Regards,
Matthieu

Hi,

I noticed that epicsUInt64 is not defined on my 64-bit system. In epicsTypes.h I see:

#if __STDC_VERSION__ >= 199901L
     typedef int8_t          epicsInt8;
     typedef uint8_t         epicsUInt8;
     typedef int16_t         epicsInt16;
     typedef uint16_t        epicsUInt16;
     typedef epicsUInt16     epicsEnum16;
     typedef int32_t         epicsInt32;
     typedef uint32_t        epicsUInt32;
     typedef int64_t         epicsInt64;
     typedef uint64_t        epicsUInt64;
#else
     typedef char            epicsInt8;
     typedef unsigned char   epicsUInt8;
     typedef short           epicsInt16;
     typedef unsigned short  epicsUInt16;
     typedef epicsUInt16     epicsEnum16;
     typedef int             epicsInt32;
     typedef unsigned int    epicsUInt32;
#endif

So I tried setting -D__STDC_VERSION__=199901L in:
configure/os/CONFIG.Common.linuxCommon

But I suspect that's the wrong way to do it, because base failed to compile:

/usr/bin/g++ -c  -D_POSIX_C_SOURCE=199506L -D_POSIX_THREADS -D_XOPEN_SOURCE=500 -D__STDC_VERSION__=199901L           -D_X86_64_  -DUNIX  -D_BSD_SOURCE -Dlinux  -D_REENTRANT   -g   -Wall      -m64     -fPIC -MMD -I. -I../O.Common -I. -I.. -I../../../include/os/Linux -I../../../include        ../cac.cpp
In file included from ../comBuf.h:34,
                  from ../cac.h:44,
                  from ../cac.cpp:39:
../../../include/osiWireFormat.h: In function ‘void WireSet(const T&, epicsUInt8*) [with T = char]’:
../comBuf.h:237:   instantiated from ‘unsigned int comBuf::push(const T*, unsigned int) [with T = char]’
../comQueSend.h:123:   instantiated from ‘void comQueSend::push(const T*, unsigned int) [with T = char]’
../comQueSend.h:206:   instantiated from here
../../../include/osiWireFormat.h:208: error: ‘tmp’ has incomplete type


But I'm sure many people are using C99. Any ideas?

Cheers,
Matt
