Subject: [PATCH] gd_bmp: fix build with uClibc
|
|
|
|
Some architectures (like ARM) don't have the long double variants of math
|
|
functions under uClibc. Add a local ceill definition in this case.
|
|
|
|
Patch status: reported upstream,
|
|
https://bitbucket.org/libgd/gd-libgd/issue/123/build-failure-agains-uclibc-arm
|
|
|
