This is caused as follows: 1. If HAVE_DECL_GETOPT is defined (getopt declaration with known prototype is detected while configuration), a declaration of getopt in "include/getopt.h" is suppressed. The author started to define HAVE_DECL_GETOPT in sim with the commit 340aa4f6872c ("sim: Check known getopt definition existence"). 2. GNU libc (2.25 or earlier)'s includes with a special purpose macro defined to declare only getopt function but due to include path (not tested while configuration), it causes to include Libiberty's "include/getopt.h". 3. If both 1. and 2. are satisfied, despite that tries to declare getopt by including , "include/getopt.h" does not do so, causing getopt function undeclared. Getting rid of "include/getopt.h" (e.g. renaming this header file) is the best solution to avoid hacking but as a short-term solution, this commit replaces getopt with getopt_long under sim/. --- sim/igen/igen.c | 6 ++++-- sim/m32c/main.c | 5 ++++- sim/ppc/dgen.c | 6 ++++-- sim/ppc/igen.c | 9 ++++++--- sim/rl78/main.c | 4 +++- 5 files changed, 21 insertions(+), 9 deletions(-) diff --git a/sim/igen/igen.c b/sim/igen/igen.c index ba856401fa9..b0a07743c24 100644 --- a/sim/igen/igen.c +++ b/sim/igen/igen.c @@ -989,6 +989,7 @@ main (int argc, char **argv, char **envp) char *real_file_name = NULL; int is_header = 0; int ch; + static const struct option longopts[] = { { 0 } }; lf *standard_out = lf_open ("-", "stdout", lf_omit_references, lf_is_text, "igen"); @@ -1162,8 +1163,9 @@ main (int argc, char **argv, char **envp) printf (" -t output itable\n"); } - while ((ch = getopt (argc, argv, - "B:D:F:G:H:I:M:N:P:T:W:o:k:i:n:hc:d:e:m:r:s:t:f:x")) + while ((ch = getopt_long (argc, argv, + "B:D:F:G:H:I:M:N:P:T:W:o:k:i:n:hc:d:e:m:r:s:t:f:x", + longopts, NULL)) != -1) { #if 0 /* For debugging. */ diff --git a/sim/m32c/main.c b/sim/m32c/main.c index 958ca27ab2b..5ed912ae7bc 100644 --- a/sim/m32c/main.c +++ b/sim/m32c/main.c @@ -29,6 +29,7 @@ along with this program.
