Hello, i have webcamera creative blaster webcam 3, i have enabled for it a driver for chip and for camera, and the system shows it has fixed a cam, but when i want to install software to broadcast over the web, it gives me error when i do "make", but at ./configure step everything is fine. Here is output for "make":

main_loop.o(.text+0x1a5): In function `accept_client':
/root/camserv-0.5.1/camserv/main_loop.c:145: undefined reference to `errno'
main_loop.o(.text+0xf84): In function `main_loop':
/root/camserv-0.5.1/camserv/main_loop.c:446: undefined reference to `errno'
picture_loop.o(.text+0x6a5):/root/camserv-0.5.1/camserv/picture_loop.c:315: more undefined references to `errno' follow
collect2: ld returned 1 exit status
make[1]: *** [camserv] Error 1
make[1]: Leaving directory `/root/camserv-0.5.1/camserv'
make: *** [all-recursive] Error 1
root@server:~/camserv-0.5.1#

Maybe anyone can help me fix this problem.

try:

make LDFLAGS="-L/lib"

or:

export LD_LIBRARY_PATH=/lib:$LD_LIBRARY_PATH

neither should be neccessary but for some reason the package isn't trying to link libc ( the c library)

none of commands helped

have you altered your glibc library install?

does the following command report errno as a function of the library?

Here is an output for this command :

objdump -R /lib/libc.so.6 | grep errno
0012b840 R_386_GLOB_DAT errno
0012b890 R_386_GLOB_DAT h_errno
0012b6f0 R_386_JUMP_SLOT __errno_location

post a little farther up on your error message, where it shows it invoking the compiler ( toward the end it will have the linker flags ( again, none of this should be neccessary since errno is part of glibc))

here almost all make outout:
