--- Comment #34 from Greg Chandler <chandleg at wizardsworks dot org> ---
With this set of debugs in gcc.cc:execute
/* Run each piped subprocess. */
fprintf (stdout, "Run each piped subprocess\n");
fprintf (stdout, "progname: %s\ntemp_filename: %s\n", progname, temp_filename);
pex = pex_init (PEX_USE_PIPES | ((report_times || report_times_to_file)
? PEX_RECORD_TIMES : 0),
progname, temp_filename);
fprintf (stdout, "pex: %s\n", pex);
if (pex == NULL)
fatal_error (input_location, "%<pex_init%> failed: %m");
for (i = 0; i < n_commands; i++)
{
const char *errmsg;
int err;
const char *string = commands[i].argv[0];
/*####HERE####*/
fprintf (stdout, "commands.prog: %s\nstring: %s\n", commands[i].prog, string);
fflush(stdout);
errmsg = pex_run (pex,
((i + 1 == n_commands ? PEX_LAST : 0)
| (string == commands[i].prog ? PEX_SEARCH : 0)),
string, CONST_CAST (char **, commands[i].argv),
NULL, NULL, &err);
fprintf (stdout, "errmsg: %s\n", errmsg);
fflush(stdout);
fprintf (stdout, "commands[i].prog: %s\n", commands[i].prog);
fflush(stdout);
fprintf (stdout, "PEX_SEARCH: %o\n", PEX_SEARCH);
fflush(stdout);
I get this:
root@bigbang:/tmp# mount /dev/sdc1 /mnt ; /mnt/gcc 1.c ; umount /mnt
Start of execute function
wrapper_string: (null)
Test of find_a_program: (null)
Run each piped subprocess
progname: gcc
temp_filename: /tmp/ccdkrjmN.s
pex:
commands.prog: cc1
string: cc1
errmsg: posix_spawnp
commands[i].prog: cc1
PEX_SEARCH: 2
gcc: fatal error: cannot execute1 'cc1': posix_spawnp: No such file or
directory
compilation terminated.
I've had a hunch that from these errors it's been a path to cc1 issue for a
bit, so now that I've ruled out about everything else I gave it a try forcing
cc1 at it's full path:
errmsg = pex_run (pex,
((i + 1 == n_commands ? PEX_LAST : 0)
| (string == commands[i].prog ? PEX_SEARCH : 0)),
"/usr/libexec/gcc/alpha-linux-gnu/14.3.0/cc1",
CONST_CAST (char **, commands[i].argv),
// string, CONST_CAST (char **, commands[i].argv),
NULL, NULL, &err);
Which yielded:
root@bigbang:/tmp# mount /dev/sdc1 /mnt ; /mnt/gcc 1.c ; umount /mnt

wrapper_string: (null)

Which we should expect as the assembler call is being made with the compiler.
So tomorrow I will sit down and figure out why cc1 is being called without any
path or path searching.
