Hi all,
I already install on my WRT54G the Maxim RS 232 kit and the system works fine, I'm going to develop an application that read and write data from serial port and I start to compile the usually library that I use for my C/C++ applications (libezV24-0.1.1) .
I changed the libezV24-0.1.1 makefile but I have the following errors:

staging_dir_mipsel/bin/mipsel-linux-uclibc-gcc -c -Wall  -fPIC -O2 -D__LINUX__  -DFINAL  snprintf.c
snprintf.c: In function `conv_fp':
snprintf.c:201: warning: implicit declaration of function `fcvt'
snprintf.c:201: warning: assignment makes pointer from integer without a cast
snprintf.c:203: warning: implicit declaration of function `ecvt'
snprintf.c:203: warning: assignment makes pointer from integer without a cast
snprintf.c: In function `v24_vsnprintf':
snprintf.c:594: warning: implicit declaration of function `gcvt'
snprintf.c:594: warning: assignment makes pointer from integer without a cast

I know that fcvt and ecvt functions are not present in stdlib (toolchain_build_mipsel/uClibc-0.9.27/libc/stdlib)
so somebody can suggest me if is there library already compiled (for WRT54G/GS)  to serial port administrations?

Thank you very much

F.G.
