[PATCH] build: Fix make rule for building crc%gen.h

by Maciej Grela

The current rule for building a directory for crc%gen.h uses $(notdir $@) causing a build error: make[3]: Entering directory `/home/enki/devel/tst/osmocom-bb/src/shared/libosmocore/build-target/include' /usr/bin/mkdir -p crc16gen.h sed -e's/XX/16/g' ../../include/osmocom/core/crcXXgen.h.tpl > osmocom/core/crc16gen.h Changed to use $(dir $@) which makes more sense when calling mkdir.

cppcheck/pyflakes results for osmocom-bb

[PATCH] gsm_utils.c: cleanup + do not use dynamic memory when decoding 7bit messages

by Nico Golde

Hi, attached is a patch that cleans up gsm_7bit_decode_hdr() a little and removes the need for calloc/free. This way, this function can be used on systems that do not have the required allocation routines (e.g. a layer1 firmware). This is a bit selfish, as I personally need it :) Cheers Nico

[PATCH] Decoding UCS2 USSD

by Pavel Baturko

Hi, I create patch with added decoding of UCS2 USSD messages. Text in UCS2 is printed on 'mobile' console and status is sent to vty since there is no support of wide characters in vty. Added constants to decode GSM 7bit text when DCS is specified as 0x00, 0x01. I tested it with Russian language with several providers and all works ok. Thanks, Pavel

[PATCH] build: fix directory creation for core headers, introduced by d471a219

by Nico Golde

Attached is a patch for libosmocore that fixes the error mentioned in CABvrX2XCNRP+qhdW+b8eiWzCDJGVeC5vEaHfO3tOTsjaUg96Lw(a)mail.gmail.com. I guess this should be fixed in libosmocore and not osmocom-bb and the included shared library should be updated. Cheers Nico
