I had to go down this road too recently. The portage man pages mention |
| 26 |
the two ways and recommend the completely non-obvious one that melted my |
| 27 |
brain. It works like this: |
| 28 |
|
| 29 |
$ cat /etc/portage/package.env |
| 30 |
=app-emulation/virtualbox-5.0.6 vbox-makeopts |
| 31 |
=app-emulation/virtualbox-5.0.6-r1 vbox-makeopts |
| 32 |
|
| 33 |
$ cat /etc/portage/env/vbox-makeopts |
| 34 |
MAKEOPTS="-j2 -l4" |
| 35 |
|
| 36 |
All the atoms listed in package.env (2 virtual box ebuilds in this case) |
| 37 |
will apply the environment settings in a file called vbox-makeopts. I |
| 38 |
had to do this because virtualbox-5 has a weird parallel build bug - it |
| 39 |
often fails with j=1 or j>2 but never with j=2. Odd. |
| 40 |
|
| 41 |
|
| 42 |
The other method is very obvious but somehow not recommended: |
| 43 |
|
| 44 |
$ ls -l /etc/portage/env/mail-client |
| 45 |
-rw-r--r-- 1 root root 92 Sep 25 17:00 thunderbird-38.2.0 |
| 46 |
-rw-r--r-- 1 root root 92 Oct 1 14:52 thunderbird-38.3.0 |
| 47 |
|
| 48 |
$ cat /etc/portage/env/mail-client/thunderbird-38.2.0 |
| 49 |
LDFLAGS="${LDFLAGS} |
| 50 |
-Wl,-rpath,/usr/lib/thunderbird,-rpath,/usr/lib/thunderbird/components" |
| 51 |
|
| 52 |
|
| 53 |
The dir and version structure of env/<pkg>-<version> is compared to |
| 54 |
what is being merged (IIRC $P, $PN, $PV all work) and the env in the |
| 55 |
file is applied. |
