Image.magick failed when convert jpg to png

[jyz19880823]

1. Image image;
2. image.read(srcBlob);
3. image.magick("PNG");
4. image.write(&blob);

I use ImageMagick++ (6.7.8.9) with node, it works without line 3.
If add line 3 to convert JPG to PNG, it will crash.

node: symbol lookup error: /root/gif-magick/build/Debug/im.node: undefined symbol: _ZN6Magick5Image5writeEPNS_4BlobERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE

PS: the codes works fine on mac os 10.15, but crash on centos.

IM v6.7.8.9 is very very very old. I suggest you upgrade.

I don't know what "node" is.

That symbol looks weird. Is that a run-time error, or compile or link?

the version is the only one on the server environment.
Node is the nodejs, which can work with c++ by addons.
it is run-time error. if add some condition to pass by image.magick('png'), it works all right.
I will try to upgrade the package~
thanks.
