發(fā)布時(shí)間:2020-04-10 11:01:30 來(lái)源:網(wǎng)絡(luò) 閱讀:5661 作者:BlueMiaomiao 欄目:編程語(yǔ)言

下載libpng源碼

wget https://sourceforge.net/projects/libpng/files/libpng16/1.6.36/libpng-1.6.36.tar.xz

修改png.c文件

if (png_sRGB_checks[i].is_broken != 0)
{
     /* These profiles are known to have bad data that may cause
        * problems if they are used, therefore attempt to
        * discourage their use, skip the 'have_md5' warning below,
        * which is made irrelevant by this error.
        */
     // 注釋掉下邊這兩行代碼
     // png_chunk_report(png_ptr, "known incorrect sRGB profile",
     //     PNG_CHUNK_ERROR);
}

編譯安裝

sudo apt install zlib* -y
sudo apt install gcc make cmake -y
./configure && make -j && sudo make install
