| Subject: [PATCH] Add missing limits.h include for UINT_MAX |
| MIME-Version: 1.0 |
| Content-Type: text/plain; charset=UTF-8 |
| Content-Transfer-Encoding: 8bit |
| |
| encode-basic.c uses 'UINT_MAX', which is available in the 'limits.h' |
| header. |
| |
| In some configurations that build with zlib from [1], by chance |
| limits.h gets indirectly included when including 'z-imp.h' (the |
| includes are: 'z-imp.h' -> 'zlib.h' -> 'zconf.h' -> 'limits.h'), so |
| the build succeeds. |
| |
| When using other zlib implementations however (for example from [2]), |
| limits.h is not necessarily included indirectly, which leads to the |
| build failing in the following way: |
| |
| source/fitz/encode-basic.c: In function 'deflate_write': |
| source/fitz/encode-basic.c:343:27: error: 'UINT_MAX' undeclared (first use in this function) |
| 343 | newbufsize = n >= UINT_MAX ? UINT_MAX : deflateBound(&state->z, n); |
| | ^~~~~~~~ |
| source/fitz/encode-basic.c:26:1: note: 'UINT_MAX' is defined in header '<limits.h>'; did you forget to '#include <limits.h>'? |
| |
| Add the missing include, so that the build succeeds no matter if zlib |
| indirectly includes 'limit.h' or not. |
| |
| Similarly, also add it in output-ps.c where it's also missing. |
