 Posted: Sat Aug 02, 2003 8:37 pm Post subject: determine cflags of installed packages |
 |
|
how could i get a list of all packages installed, that are not compiled with the current cflags?
need to parse all the /var/db/pkg/<category>/<package>/CFLAGS files, but i am not experienced enough to get it working.
The main problem is: emerge -e world b0rked at one package and i issued some other emerge commands to get it fixed. right. bad idea. now i cannot resume the previous emerge process anymore.
EDIT: altered subject.

so, this is what i've got so far:
| Code: | cd /var/db/pkg ; for name in $(find . -name CFLAGS); do if grep -v " -funroll-loops " $name >/dev/null ; then echo $name; fi; done
|
it will return a list like the following:
| Code: | ./sys-kernel/development-sources-2.6.0_beta1/CFLAGS
./sys-kernel/ck-sources-2.4.20-r6/CFLAGS
./sys-kernel/ck-sources-2.4.21-r3/CFLAGS
./dev-cpp/gtkmm-1.2.9-r2/CFLAGS
./dev-cpp/gnomemm-1.2.3-r1/CFLAGS
./dev-php/smarty-2.5.0/CFLAGS
|
but i can't figure out how to use sed to display only the package name

| Code: | | cd /var/db/pkg ; for name in $(find . -name CFLAGS); do if grep -v " -funroll-loops " $name >/dev/null ; then echo $name | sed 's/\/CFLAGS$//g;s/^.*\///g' ; fi; done |
I think this works. I used sed to get rid of the unwanted lines. First I get the last /CFLAGS out (search and 'replace'), then I can delete everything before the /. |

really nice. now the last problem is to strip off the package version, because emerge won't work with it.

If you put an equals sign before the package name and version, it'll emerge that particular version, if that would help.

ah GREAT!
thanks to both of you.
For future reference, the final hack looks like this:
| Code: | | cd /var/db/pkg ; for name in $(find . -name CFLAGS); do if grep -v " -funroll-loops " $name >/dev/null ; then echo $name | sed 's/\/CFLAGS$//g;s/.\//=/' ; fi; done > /root/packages |
