File jasper-2.0.17.patch of Package kdelibs4
From: Wolfgang Bauer <wbauer@tmo.at> Subject: Fix build with jasper 2.0.17 or higher The `cnt` parameters have been changed from int to unsigned in 2.0.17, and later to size_t in 3.0 (which also changed the return codes to ssize_t), resulting in -fpermissive errors. Additionally, `char *buf` was changed to `const char *buf` for the write function in 2.0.20. And jp2_encode() is an internal function not to be used by applications (it's no longer exported at all in 3.0), so use jas_image_encode() instead. diff --git a/kimgio/jp2.cpp b/kimgio/jp2.cpp --- a/kimgio/jp2.cpp +++ b/kimgio/jp2.cpp @@ -103,13 +103,13 @@ static void jas_stream_initbuf(jas_stream_t *stream, int bufmode, char *buf, stream->bufmode_ |= bufmode & JAS_STREAM_BUFMODEMASK; } -static int qiodevice_read(jas_stream_obj_t *obj, char *buf, int cnt) +static ssize_t qiodevice_read(jas_stream_obj_t *obj, char *buf, size_t cnt) { QIODevice *io = (QIODevice*) obj; return io->read(buf, cnt); } -static int qiodevice_write(jas_stream_obj_t *obj, char *buf, int cnt) +static ssize_t qiodevice_write(jas_stream_obj_t *obj, const char *buf, size_t cnt) { QIODevice *io = (QIODevice*) obj; return io->write(buf, cnt); @@ -385,7 +385,8 @@ write_image( const QImage &image, QIODevice* io, int quality ) // use sprintf for locale-aware string char rateBuffer[16]; sprintf(rateBuffer, "rate=%.2g\n", (quality < 0) ?
