pod geos error about geoswift

[vfn]

Hi @badmonkeyemail,

If you look at the second last line of the log you posted above, ld: can't map file, errno=22 file '/usr/local/opt/libxml2/lib' for architecture x86_64 it looks to be an issue with libxml2

Please share the whole log, if possible as it will make it easier to understand where the problem is

@badmonkeyemail, can you please provide your Podfile? And if possible, to create a sample project that I could clone and look at the issue.

[badmonkeyemail]

Hi @vfn,
Thank you for your reply.

I used the geoswift project, and I deleted GEOSwift.xcworkspace file because it's error:

diff: /Podfile.lock: No such file or directory
diff: /Manifest.lock: No such file or directory
error: The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation.

my podfile is

Uncomment this line to define a global platform for your project

platform :ios, ’10.0’

use_frameworks!

target 'GEOSwift' do
pod 'GEOSwift'
pod 'geos'
pod 'CocoaLumberjack'
end

target 'GEOSwiftTests' do
pod 'GEOSwift'
pod 'geos'
pod 'CocoaLumberjack'
end

Thank you for your help.

[vfn]

Hi @badmonkeyemail, I don't believe that deleting GEOSwift.xcworkspace was the correct action. The error message clearly stated what was the issue:

diff: /Podfile.lock: No such file or directory
diff: /Manifest.lock: No such file or directory
error: The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation.

You should first run pod install and then you can try to build the project again.

If that doesn't solve your problem, please create a sample project and share the URL here.

Thanks!

[badmonkeyemail]

Hi @vfn ,
I upload my project. https://github.com/badmonkeyemail/test-geoswift
Please help.
Thank you.

[vfn]

@badmonkeyemail, Thank you for creating the repo. I cloned it and it worked just fine on my machine. After cloning, I run pod install, and then opened GEOSwift.xcworkspace. The project builds with no issues. ¯_(ツ)_/¯

[badmonkeyemail]

Hi @vfn , it's too strange! What should I do? I guess the problem is maybe my environment or setting. This is parameters of my mac:
mac 10.12.5
Xcode 8.3.2 (8E2002)

gcc-4.9 (Homebrew GCC 4.9.4) 4.9.4
--- I don't use clang，because https://svn.osgeo.org/geos/trunk/INSTALL said "OS/X 10.6, compile with gcc-4.0 rather than the default gcc that comes with XCode. CC=gcc-4.0 CXX=g++-4.0 ./configure" ,
and I used clang at first but it's still error.

ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14]
gem 2.6.7
pod 1.2.1
Homebrew 1.2.3
libxml2 2.9.4_3

Anything wrong?

Thanks.

[vfn]

@badmonkeyemail I can't see anything wrong with your setup. Could you explain what you are trying to do? Are you trying to integrate GEOSwift into an existing project or are you planing to do some development on the GEOSwift code itself?

[badmonkeyemail]

@vfn , My app need to draw vector data and my render engine supports geometry object. For simple vector data, like 'Polygon((0 0, 10 0, 10 10, 0 10, 0 0))', is ok, but same special complex data, which has a hole in the polygon or multi features, displays wrong. So I need geoSwift to parse vector data to correct geometry object. Is there anything else I can do without geoSwift?

[vfn]

@badmonkeyemail, could you try cloning the GEOSwift repo again? Then on terminal, type pod install and the proceed to open the GEOSwift.xcworkspace file.

Let me know it the pod will fail to build. if it fails, please create a repo and push this new project

[badmonkeyemail]

Hi @vfn , I think the problem is about configure geos, the log said,

[badmonkeyemail]

Hi @vfn , My friend compiled it okey. I feel very sad. Your project has no problem, its my fault.
I will colse it, and thanks your help again.

[vfn]

@badmonkeyemail no problems! Please consider creating a pull request with your changes once you've finished them.
