[Mingw-users] Current MinGW GCC gives no output on failures?

[Clive C. <cl...@cr...>]

Hi,

I'm having trouble with failed compiles not giving any output at all
(unless the input source file is completely missing).

I've used mingw-get to install everything on my system, and it appears that
gcc/g++ simply don't output errors anymore? Is there something I'm missing
here?

I've attached a screenshot.

Thanks,
Clive

With a zero byte a.c, I've consistently got:
$ gcc a.c
e:/mingw/bin/../lib/gcc/mingw32/4.8.1/../../../libmingw32.a(main.o):(.text.startup+0xa7): 
undefined reference to `WinMain@16'
collect2.exe: error: ld returned 1 exit status

If you compile-only using -c, then the zero byte a.c gives a 406 
byte a.o file. Using installed gcc 4.8.1, I didn't install 
everything though.

The zero byte was a simplified example. Any errors, at all, for any reason
(eg missing includes, for instance) give me no output, no indication of
error, no result file, nothing printed (exit code 1).

Could be a configuration problem. See output below. COLLECT_GCC is 
different, I guess the wrapper failed to call gcc proper.

$ gcc -v a.c
Using built-in specs.

This is on a fresh, clean install of Windows, MinGW is all that is
installed on that machine, I used MinGW's own installer.
So if this is a configuration problem, it means the installer is broken.

For those that are interested, or if you come across the same problems:
 I've solved my own problem (I'm able to continue working) by using this
MinGW build:

http://nuwen.net/mingw.html

Instead of the binaries on MinGW's own site.

Looks like something is wrong with your cc1.exe, it doesn't even
announce itself, as it should under -v.

Re: [Mingw-users] Current MinGW GCC gives no output on failures?

[Clive C. <cl...@cr...>]

The errors I've experienced are on a box that's a fresh windows install
(server 2012) and then the following scripts executed in order to install
MinGW, after which it doesn't display errors.

So, to reproduce : Clean/New windows installation, then run the following:

:: Download

powershell -Command "(New-Object System.Net.WebClient).DownloadFile('
http://sourceforge.net/projects/mingw/files/Installer/mingw-get/mingw-get-0.6.2-beta-20131004-1/mingw-get-0.6.2-mingw32-beta-20131004-1-bin.zip/download',
'C:\Windows\Temp\mingw-get.zip')" <NUL
powershell -Command "(New-Object System.Net.WebClient).DownloadFile('
http://downloads.sourceforge.net/sevenzip/7z920-x64.msi',
'C:\Windows\Temp\7z920-x64.msi')" <NUL

:: Extract

msiexec /qb /i C:\Windows\Temp\7z920-x64.msi
cmd /c ""C:\Program Files\7-Zip\7z.exe" x C:\Windows\Temp\mingw-get.zip
-oC:\MinGW"
msiexec /qb /x C:\Windows\Temp\7z920-x64.msi

:: Update & Install Components

C:\MinGW\bin\mingw-get update
C:\MinGW\bin\mingw-get install mingw-get
C:\MinGW\bin\mingw-get upgrade --reinstall mingw-get
C:\MinGW\bin\mingw-get update
C:\MinGW\bin\mingw-get install gcc g++ mingw32-make zlib

Not sure how this is relevant.  I'm telling you that judging by the
output of "gcc -v" that you presented, the problem starts with the
invocation of cc1.exe: it didn't display its banner, which it should
have done given the -v switch.

So either cc1.exe was not found (unlikely), or it's corrupted, or
Windows/gcc were unable to run it.  (Is there anything pertinent in
the Windows Event Log?)

Here's how cc1 announces itself in the same command on my machine:

  GNU C (GCC) version 4.8.1 (mingw32)
	  compiled by GNU C version 4.8.1, GMP version 5.1.2, MPFR version 3.1.2,
  MPC version 1.0.1
  GGC heuristics: --param ggc-min-expand=100 --param ggc-min-heapsize=131072
