PORT BUILD OPTION
|
|
|
|
|
=================
|
|
|
|
|
|
|
|
|
|
There are two useful options are suggested and available for this port of
|
|
|
|
|
giftool. You can specify it following "make clean".
|
|
|
|
|
|
|
|
|
|
make RETVALUE=yes
|
|
|
|
|
-----------
|
|
|
|
|
Giftool does not return value from main(), so it is impossible to use this
|
|
|
|
|
tools in programs like make(1) or pipes.
|
|
|
|
|
This option is suggested by Sergei Chechetkin <csl@whale.sunbay.crimea.ua>.
|
|
|
|
|
|
|
|
|
|
make MALLOCSIZE=yes
|
|
|
|
|
---------------
|
|
|
|
|
Giftool 1.0 or some earlier version cause segmentation fault about some
|
|
|
|
|
images. Something about pre-read seems to be bad, so make malloc size
|
|
|
|
|
bigger to improve that.
|
|
|
|
|
This option is suggested by Hidetoshi Shimokawa <simokawa@sat.t.u-tokyo.ac.jp>.
|
|
|
|
|
|
|
|
|
|
You can specify all options such as 'make RETVALUE=yes MALLOCSIZE=yes'.
