[ptxdist] Linker problem: libpng-1.2.50, ptxdist-2012.12.0, and new atom toolchain i686-atom-linux

["Schenk, Gavin" <G.Schenk@eckelmann.de>]

Hi,

yesterday I read about the new toolchain, that has Atom optimization by default.

I decided to give it a try and:
Compiled the new toolchain: gcc-4.6.2-glibc-2.14.1-binutils-2.21.1a-kernel-2.6.39-sanitized
Migrated my project: 2012.10.0 to 2012.12.0
Update Kernel and rt-patchstack: 3.4.2 to 3.6.10

Now the compilation fails on libpng 1.2.50 that is the same version as in ptxdist-2012.10.0.

On my old system content of libpng.vers was:
PNG12_0 {global:
png_libpng_ver;
png_pass_start;
png_pass_inc;
png_pass_ystart;
png_pass_yinc;
png_pass_mask;
png_pass_dsp_mask;
png_access_version_number;
png_set_sig_bytes;
png_sig_cmp;
png_check_sig;
png_create_read_struct;
png_create_write_struct;
png_get_compression_buffer_size;
png_set_compression_buffer_size;
png_reset_zstream;
png_create_read_struct_2;
png_create_write_struct_2;
png_write_chunk;
png_write_chunk_start;
png_write_chunk_data;
png_write_chunk_end;
png_create_info_struct;
png_info_init;
png_info_init_3;
png_write_info_before_PLTE;
png_write_info;
png_read_info;
png_convert_to_rfc1123;
png_convert_from_struct_tm;
png_convert_from_time_t;
png_set_expand;
png_set_expand_gray_1_2_4_to_8;
png_set_palette_to_rgb;
png_set_tRNS_to_alpha;
png_set_gray_1_2_4_to_8;
png_set_bgr;
png_set_gray_to_rgb;
png_set_rgb_to_gray;
png_set_rgb_to_gray_fixed;
png_get_rgb_to_gray_status;

Now the content is:
PNG12_0 {global:
local: *; };

The libpng.sym file is empty. Can you please assist me solving this error?
