[maemo-developers] The code using Libcurl can not be linked properly

[From: Yao Wang]

Hi,
    Everyone. I am developping an appliacation on CHINOOK.
    Because my code used some functions provided by Libcurl, I revised the
Makefile  to the following

> CC = gcc
>
> CFLAGS = `pkg-config --cflags gtk+-2.0 hildon-1`  -ansi -Wall -ggdb
>
> CFLAGS_CURL = -I/scratchbox/devkits/maemo3-tools/include
>
> LIBS = `pkg-config --libs gtk+-2.0 hildon-1`
>
> LIB_CURL = -L/scratchbox/devkits/maemo3-tools/lib -lcurl -Wl,-rpath
> -Wl,/scratchbox/host_shared/lib/ -Wl,-rpath -Wl,/scratchbox/tools/lib/
> -Wl,-rpath -Wl,/scratchbox/devkits/maemo3-tools/lib/
> -L/scratchbox/devkits/maemo3-tools/lib -lidn -lssl -lcrypto -ldl -lssl
> -lcrypto -ldl -lz
>
> TARGET =        GalleryBrowser
>
> SOURCES = src/main.c src/xxxx.c
>
> $(TARGET): $(SOURCES)
>         $(CC) -o $(TARGET) $(SOURCES) $(CFLAGS) $(CFLAGS_CURL) $(LIBS)
> $(LIB_CURL)
>

The CFLAGS_CURL and LIB_CURL  are generated by curl-config.

After compiling and linking, I got a error messege same as following link:

https://bugs.maemo.org/show_bug.cgi?id=2261#add_comment

Unfortuantely, no solution is provided in this page.
Someone in this page mentioned to remove -lidn. When I removed the -lidn,
the linking process is OK. However, if I run the program, I will get a error
messge:

" relocation error: /scratchbox/host_shared/lib/libc.so.6: symbol
_dl_starting_up, version GLIBC_PRIVATE not defined in file ld-linux.so.2
with link time reference"

Thus, is there anyone who can help me?

Thanks in advance.
