Subject: [PATCH] buildsys: fix static configuration and building
|
||
|
|
|
||
|
|
In case of uClibc librt depends on libpthread. In particular
|
||
|
|
timer_create() function uses pthread_XXX(). That means in case
|
||
|
|
of static builds it's required to link not librt alone but
|
||
|
|
together with libpthread. So if checking timer_create function
|
||
|
|
in librt fails, it is necessary to check if timer_create function
|
||
|
|
successfully links with "-lpthread".
|
||
|
|
|
||
|
|
That issues was spotted in Buldroot autobuilder failures:
