[gpsd-dev] [PATCH] Fix ubx_mode link error when reconfigure=false


From: spdawson
Subject: [gpsd-dev] [PATCH] Fix ubx_mode link error when reconfigure=false
Date: Sun, 8 Dec 2013 09:11:34 +0000

From: Simon Dawson <address@hidden>

When reconfigure is false, the link step fails as follows.


/scratch/peko/host/usr/bin/arm-buildroot-linux-uclibcgnueabi-gcc -o gpsd 
-pthread 
--sysroot=/scratch/peko/host/usr/arm-buildroot-linux-uclibcgnueabi/sysroot 
gpsd.o ntpshm.o shmexport.o dbusexport.o -L. 
-L/scratch/peko/host/usr/arm-buildroot-linux-uclibcgnueabi/sysroot/usr/lib -lrt 
-lbluetooth -ldbus-1 -lgpsd -lusb-1.0 -lbluetooth -lgps -lm -ldbus-1 -lpthread 
-lrt
./libgpsd.so: undefined reference to `ubx_mode'
collect2: error: ld returned 1 exit status
scons: *** [gpsd] Error 1
scons: building terminated because of errors.


The problem appears to be a failure to guard a call to ubx_mode with a
RECONFIGURE_ENABLE ifdef.
