Subject: [Bug target/14291] New: -fprofile-arcs fails (unresolved symbol)
Date: Wed, 25 Feb 2004 15:03:00 -0000	[thread overview]
Message-ID: <20040225150311.14291.xtrochu@yahoo.com> (raw)

C:\devel\gcc\testsuite>gcc -fprofile-arcs -o test test.c
C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp/ccE7aaaa.o(.text+0x38):test.c: undefined 
reference to `ftruncate'

The following patch correct the issue :

diff -u5 -rNdw gcc-cvs/gcc/gcc/gcov-io.h src/gcc/gcov-io.h

 static inline void
 gcov_truncate (void)
 {
+#ifndef __MINGW32__
   ftruncate (fileno (gcov_var.file), 0L);
+#else
+  /* ftruncate() is not available in msvcrt */
+  fpos_t pos = 0L;
+  fsetpos(gcov_var.file, &pos);
+#endif
 }
 #endif
 
 #endif /* IN_LIBGCOV >= 0 */
 
But maybe adding ftruncate to libiberty is preferable.
