Reactivecocoa: metamacros.h file not found

[szweier]

@ashfurrow I was trying to update to CocoaPods 1.0.0 and it seems to result in a metamacros.h file not found error for RAC 4.0.1. I noticed the 4.0.1 pod spec doesn't have the same prepare command as the 2.3 pod spec does.

"prepare_command": "    find . \\( -regex '.*EXT.*\\.[mh]$' -o -regex '.*metamacros\\.[mh]$' \\) -execdir mv {} RAC{} \\;\n    find . -regex '.*\\.[hm]' -exec sed -i '' -E 's@\"(EXT.*|metamacros)\\.h\"@\"RAC\\1.h\"@' {} \\;\n    find . -regex '.*\\.[hm]' -exec sed -i '' -E 's@<ReactiveCocoa/(EXT.*)\\.h>@<ReactiveCocoa/RAC\\1.h>@' {} \\;\n",
  "

I'm not sure this is what's needed to fix the issue but it looks like it might be. When I upgrade to CocoaPods 1.0.0 the metamacros.h issue shows up unless I drop down to RAC 2.3

Thanks for any help you can provide.

There is a solution that use cocoa pods 1.0?

[zigdanis]

Maybe someone has custom podspec that could fix this for cocoapods 1.0.0?

pod 'ReactiveCocoa', :podspec => 'https://gist.githubusercontent.com/PaulTaykalo/04f8e2ee25b9d57f03455ccafd541b34/raw/e94f3bec7a9450ecd0f0cdc9b4899deb0b91d758/ReactiveCocoa.podspec.json'

Simply changed "prepare_command"

// "prepare_command": "sed -i '' 's@<ReactiveCocoa/\\(.*\\)>@\"\\1\"@g' ReactiveCocoa/ReactiveCocoa.h",
  "prepare_command": "    find . \\( -regex '.*EXT.*\\.[mh]$' -o -regex '.*metamacros\\.[mh]$' \\) -execdir mv {} RAC{} \\;\n    find . -regex '.*\\.[hm]' -exec sed -i '' -E 's@\"

Thanks to @szweier @zigdanis @scinfu

Ok I found solution to install ReactiveCocoa without problems. So issue is related to new version of sed tool. All you need to do is uninstall sed probably installed through brew. So jus run command:

brew uninstall sed

Then perpare_command will use right version of sed. To make sure that you have old version of sed run command: $ sed --version

And the output should be like this:

sed: illegal option -- -
usage: sed script [-Ealn] [-i extension] [file ...]
   sed [-Ealn] [-i extension] [-e script] ... [-f script_file] ... [file ...]

I've extended Paul Takyalo's answer to RAC 4.2.2 for Swift 2.3. Put this in your podfile:

pod 'ReactiveCocoa', :podspec => 'https://gist.githubusercontent.com/andrewschreiber/4fd444c08e8c8e876f06bb3a8ae45f2e/raw/72798f6fd81a124b0eaac52c6484725fbe9f5330/ReactiveCocoa.podspec.json'

This issue apearred again for me with ReactiveObjc:

'metamacros.' file not found

I've tried all the options above here, even tried to create an own fork with a custom podspec, but without success. Anyone else with the same problem and a solution here?

[yfGit]

pod 'Mantle'
pod 'ReactiveCocoa'

The have the same file with name "metamacros.h"

[szweier]

Yea using Mantle + ReactiveCocoa seems to be the issue here. When using both I moved to using ReactiveCocoa as a submodule. We've since moved away from Mantle which allowed us to bring ReactiveCocoa back in using CocoaPods. Not that this is a great answer but it should explain why anyone is seeing this issue.
