help me pinpoint the problem in my c++ compiler!

mrchaos · 05-02-2006, 10:04 PM

for quite a long duration now I have had problems with my C++ compiler (g++ version 3.6.6). Here's the latest error I receive when compiling the mythtv plugins:

Code:

I can supply more errors that I receive (most likely stemming from my gcc) if need be. However, if you are experienced in writing or compiling c++ and can tell me what might be wrong, let me know! Thanks.

(if you need more info also let me know)

You're using ccache. Disable it and then try again to eliminate the possibility that ccache is causing the problem.

this may seem rather base, but how does one disable ccache in the compiler?

**edit**
I've tried setting the boolean environment variable CCACHE_DISABLE to 1, and it hasn't worked

tomdkat · 05-03-2006, 11:32 AM

Is the use of ccache something controlled by the configure script used to configure the build settings for what you're compiling?

Peace...

mrchaos · 05-03-2006, 07:03 PM

unfortunately, no... there is no --disable-ccache or --disable-distcc option available in the configure script.

mrchaos · 05-11-2006, 02:56 PM

***bump***

tomdkat · 05-11-2006, 07:39 PM

Have you asked about this on the MythTV mailing list?

Peace...

mrchaos · 05-12-2006, 09:24 PM

it's far more than just mythtv, this is a problem with my compiler... here's another installment of this drama:

Code:

zax@ZAXCOMP:~/Desktop/gnomad2-2.8.3$ sudo ./configure
checking for a BSD-compatible install... /usr/bin/ginstall -c
checking whether build environment is sane... yes
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking whether make sets $(MAKE)... (cached) yes
checking for a BSD-compatible install... /usr/bin/ginstall -c
checking for pkg-config... /usr/local/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for GN... yes
checking for gtk+-2.0 >= 2.6.0... checking for TAG... Package id3tag was not found in the pkg-config search path.
Perhaps you should add the directory containing `id3tag.pc'
to the PKG_CONFIG_PATH environment variable
No package 'id3tag' found
checking for style of include used by make... GNU
checking for gcc... gcc
checking for C compiler default output file name... a.out
checking whether the C compiler works... yes
checking whether we are cross compiling... no
checking for suffix of executables...
checking for suffix of object files... o
checking whether we are using the GNU C compiler... yes
checking whether gcc accepts -g... yes
checking for gcc option to accept ANSI C... none needed
checking dependency style of gcc... gcc3
checking how to run the C preprocessor... /lib/cpp
configure: error: C preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details.

once again there seems to be a problem with my cpp library. any hints on how to fix this would be great

it seems that the config.log is far to long to post, so if any part of it may be useful let me know

btmiller · 05-12-2006, 10:38 PM

I'd suggest that you take a look at the config.log and see what the exact error is (it's usually towards the end of the file). Also, can you try to compile this simple C++ program:

Code:

#include <iostream>

using namespace std;

int main(void)
{
   cout << "Hello, world." << endl;
   return 0;
}

This will produce an executable that will print "Hello, world." on the console when run. Save the code into a file called prog1.cpp and compile with:

Code:

g++ prog1.cpp -o prog1

Does it work with no errors? If not, what are the errors?

Also, there's no such g++ version as 3.6.6 -- did you mean 3.3.6? What version of Slackware are you running on?

here's a new addition:

Code:

bash-3.00# make

make[1]: Leaving directory `/home/zax/Programs/ivtv-0.6.2/driver'

bash-3.00#

this may be different though... perhaps my v4l is not properly compiled into my kernel

Let me know! thanks!
