After fetching current git code and compiling with gcc 4.3.3 got errors
Here is fix, so rstp compile fine with gcc 4.3.3
bridge_track.c and main.c have functions where is return value not checked.
Because of -Werror it won't compile.
Example:
gcc -Wall -Werror -O2 -g -D_REENTRANT -D__LINUX__ -DVERSION=0.16 -DBUILD=1 -I. -I./include -I./rstplib -c -o
main.o main.c
cc1: warnings being treated as errors
main.c: In function 'main':
main.c:81: error: ignoring return value of 'daemon', declared with attribute
warn_unused_result
Other fix is missing header file
gcc -Wall -O2 -g -D_REENTRANT -D__LINUX__ -DVERSION=0.16 -DBUILD=1 -I. -I./include -I./rstplib -c -o
netif_utils.o netif_utils.c
netif_utils.c: In function 'get_bridge_portno':
netif_utils.c:130: error: 'INT_MAX' undeclared (first use in this function)
netif_utils.c:130: error: (Each undeclared identifier is reported only once
netif_utils.c:130: error: for each function it appears in.)
