我正在尝试设置Lambda层,以通过Graphicsmagick向图像添加水印。但是,我在使二进制文件与库一起工作时有些卡住,那么如何在子进程中设置指向库的链接?
到目前为止,我已经使用以下选项构建了Graphicsmagick二进制文件:
./configure --prefix=/opt/graphicsmagick --enable-shared=no --enable-static=yes --disable-shared --disable-installed
基本上遵循了此answer上的说明和此Gist上的想法。但是,任何一种都不与将二进制文件作为层运行有关。所以想知道也许我在这里缺少一些细节吗?
从我的处理程序中获取代码:
module.exports.run = async (event, context, callback) => {
process.env['IM_PATH'] = '/opt/graphicsmagick/bin/'
process.env['LD_LIBRARY_PATH'] = '/opt/graphicsmagick/lib'
process.env['DYLD_LIBRARY_PATH'] = '/opt/graphicsmagick/lib'
process.env['MAGICK_HOME'] = '/opt/graphicsmagick/'
...
const graphicsmagick = '/opt/graphicsmagick/bin/gm'
const graphicsmagickArgs = [
'-dissolve', '15',
'-tile',
watermark,
inputImage,
output,
]
spawn(graphicsmagick, graphicsmagickArgs, { stdio: 'inherit' })
.on('close', () => console.log('success'))
.on('error', error => console.log('error', error))
...
}
我还尝试过使用环境变量运行exec,如下所示:
exec('/opt/graphicsmagick/bin/gm', { env:
{
'IM_PATH': `/opt/graphicsmagick/bin/`,
'LD_LIBRARY_PATH': '/opt/graphicsmagick/lib',
'DYLD_LIBRARY_PATH': '/opt/graphicsmagick/lib',
'MAGICK_HOME': `/opt/graphicsmagick/`,
}}, (err, stdout, stderr) => {
console.log('error', err)
console.log('stdout', stdout)
console.log('stderr', stderr)
})
该图层运行Graphicsmagick,但未找到库文件夹。我在控制台中收到以下错误:
/opt/graphicsmagick/bin/gm: error while loading shared libraries:libpng15.so.15: cannot open shared object file: No such file or directory
