This is a list of failures and exits that one may experience when porting software to IRIX. This list may include methods to overcome these failures.
Issue: (.text.startup+0x7e0): undefined reference to `dirname'
Fix: Run export LIBS="-lgen" before running ./configure.
Issue: With software using Boost, exiting due to a bad context for shared_ptr
Fix: Prepend boost:: to all failing references to shared_ptr
Issue: Compiler complaining about something being used or referenced in the wrong way
Example:
Fix: Could be that the code uses a name for something that is named the same as something in the OS. Reduce the context by prepending :: to the item name. In the above case, changing bind to ::bind resolved the issue.Code:/usr/didbs/0_1_9_n32_mips3_gcc/include/boost/bind/bind.hpp:1284:48: required from 'class boost::_bi::bind_t<boost::_bi::unspecified, int, boo$
t::_bi::list2<boost::_bi::value<const sockaddr*>, boost::_bi::value<int> > >'
tcpreceiver.cc:561:59: required from here

571 }
572 #endif // WIN32
Issue: You'd like to case a section of code to only be referenced in IRIX
Fix: Use the #define __sgi macro, then case around your code
Example:
C:#define __sgi
#... more stuff
#ifdef __sgi
# do some sgi stuff
#endif
Issue:
- Compilation fails due to unknown storage size of 'tv'
Fix: Add sys/time.hCode:
src/ftbench.c:179:22: error: storage size of 'tv' isn't known
179 | struct timespec tv;
Code:
#if defined(__sgi)
#include <sys/time.h>
#endif
Issue:
- error: 'CLOCK_SGI_CYCLE' undeclared
Fix: Add sys/ptimers.hCode:
src/ftbench.c:193:5: warning: implicit declaration of function 'clock_gettime' [-Wimplicit-function-declaration]
193 | clock_gettime( CLOCK_SGI_CYCLE, &tv );
Code:
#if defined(__sgi)
#include <sys/ptimers.h>
#endif
...
#ifdef _POSIX_CPUTIME
clock_gettime( CLOCK_PROCESS_CPUTIME_ID, &tv );
#elif defined(__sgi)
clock_gettime( CLOCK_SGI_CYCLE, &tv );
#else
clock_gettime( CLOCK_REALTIME, &tv );
#endif /* _POSIX_CPUTIME */
Issue: the code defines something by a name that's already used elsewhere (normally in IRIX /usr/include)
Fix: Give up and rename this thing everywhere in the source code
Example:
C:./makehelp < ../tf-lib/tf-help > ../tf-lib/tf-help.idx
In file included from socket.c:67:
tfio.h:156:15: error: conflicting types for 'wprintf'

----------------
Porting with RPM
Issue: you need a patch
Fix:
- Extract and duplicate the source code directory
- Fix the code and generate the patch
- diff -Naur <source code.orig> <source code> > <source code>.irix.patch
- Add a "Patch" line near the top of the specfile. Start with patch number 100.
- Patch100: freetype.sgifixes.patch
- Add "%patch" entry along with the rest of the %patch entries.
- %patch100 -p1 -b .sgifixes
Issue: "error: Failed build dependencies"
Example:
Fix:Code:error: Failed build dependencies:
libX11-devel is needed by freetype-2.10.0-3.sgugalpha.mips
- libX11 is specifically not installed by rpm (yet) in IRIX. Comment this section out in the specfile.
