configure: fix parsing issue on include_dir option
|
|
|
32391d |
|
|
|
32391d |
configure is stuck in an endless loop if '--include_dir' option is used
|
|
|
32391d |
without a value:
|
|
|
32391d |
|
|
|
32391d |
$ ./configure --include_dir
|
|
|
32391d |
./configure: line 506: shift: 2: shift count out of range
|
|
|
32391d |
./configure: line 506: shift: 2: shift count out of range
|
|
|
32391d |
[...]
|
|
|
32391d |
|
|
|
32391d |
Fix it splitting 'shift 2' into two consecutive shifts, and making the
|
|
|
32391d |
second one conditional to the number of remaining arguments.
|
|
|
32391d |
|
|
|
32391d |
A check is also provided after the while loop to verify the include dir
|
|
|
32391d |
exists; this avoid to produce an erroneous configuration.
