gdImagePtr not found in 2.5.0, but found in 2.4.0

[axello]

I have a strange regression bug. Version 2.5.0 gives tons of `use of undeclared type 'gdImagePtr' errors, but v2.4.0 does not.

steps taken:

• SwiftGD 2.5.0 could not find gdImagePtr
• brew reinstall gd
• remove .build
• clean project etc.
• Double-check double setting of /usr/local/lib
• downgraded to SwiftGD 2.4.0
• In the end removing the xcodeproj was the only thing which worked

However, when I upgraded to SwiftGD 2.5.0 again, removing the xcodeproj and deep cleaning the build folder, and adding the library search paths did not work anymore.

• Saved both build logs
• downgraded to SwiftGD 2.4.0

The only discrepancy I see, is that the Format.swift file is in different positions: 2.4.0: checkouts/SwiftGD/Sources/Format.swift 2.5.0: checkouts/SwiftGD/Sources/SwiftGD/Format.swift

Also, it does link with the gd library, as you can see from the compile statement.

Could you see if this problem exists with a fresh project? I just tried it (macOS Catalina) and had no problems on 2.5.0.

Sure, this was indeed an old project from 2018 (when the book came out)

I get this bug whilst on a new project following Server-side Swift: Vapor (on Catalina)

I have same problem MacOSX 10.15.3

[aryamansharda]

Having the same problem as well

[jklompje]

Having the same problem following the steps outlined for the project in Serverside Swift Vapor. Any solutions yet?

Same problem(((

[jcbriones]

Same with me. Forward to 2023. 😟 Is there any other library support for both mac and linux? 😟 I'm guessing it has something to do with the architecture?

Troubleshooting ideas

1. macOS: Make sure you have brew installed. Link
2. Try manually installing
   • macOS: libgd - Brew instructions
   • Ubuntu / deb - sudo apt-get install libgd-dev
3. Make sure your gd version is up to date.
   • macOS brew update gd
   • Ubuntu / deb - sudo apt-get upgrade libgd-dev
4. If none of the above are working, try upgrading your package manager itself.
   • macOS brew upgrade
   • Ubuntu / deb - sudo apt-get update

Note

Apologies for posting off-topic. But I'm trying to address the frustrations I see posted here.

Additional details

The Package.swift file in this project has a dependency on the gd library which must be installed on your system for this to work at all. SwiftGD is a wrapper for the gd framework. For macOS users, this will mean installing with brew.
