 |
|
I'm trying to use 'ebuild Variables' in my make.conf, like ${PN} for package name or ${PF} package full name so that I cant set a PGO (profile guided optimization) directory.
More or less CFLAGS="-fprofile-dir=/var/tmp/pgo/${PN}".
But what I get is a blank, nothing for that variable as if it didn't exist at all. Am I using it in the right place ?
My other solution is to write an script and make custom entries for every single package inside /etc/portage/env/...
So as to avoid this big work, I believe these 'ebuild variables' were made for.
For those not totally aware of PGO, PGO needs a folder for each package to store profiling data. Thanks, all ladies and gentlemen! |

Is
a file?
Can you post a sample?
Does it contain
| Code: |
CFLAGS="..............."
|
I am not sure if portage sources make.conf with every package or just once.
If the former would not
| Code: |
. /var/tmp/pgo/${PN}
|
would work?
Or maybe
| Code: |
CFLAGS="........."
PGOFLAGS=$(cat /var/tmp/pgo/${PN})
CFLAGS="${CFLAGS} ${PGOFLAGS}"
|
Just a wild guess.....

AFAIK, ebuild variables are not available in make.conf as make.conf is read before ebuilds variables are defined.
In addition, it is not valid for a build to write outside of $WORKDIR or $T as it will likely be denied by the sandbox. |

Nope, ebuild variables, as the name implies, can only be used inside ebuild contexts (ebuilds, eclasses, scripts used within ebuilds, ...). They are not defined when make.conf or other global configuration files are processed. |
