0.7.7 appears to be fine but 0.7.8 causes this issue. After a few attempts to fix it I just pinned our Gemfile with version 0.7.7.

[stephenbinns]

Belive this is related to the change made here - #174 I'm seeing similar issues on OSX as the flags aren't set by default.

If you have installed icu4c via homebrew you can configure bundle to pass the cxxflags like so

bundle config build.charlock_holmes --with-icu-dir=$(brew --prefix icu4c) --with-cxxflags=-std=c++11 

However it would be nice if this worked out of the box like 0.7.7 did

[em1l1o]

I'm having the same issue with Sonoma (14.5) installing 0.7.8 after upgrading ruby version to 3.3.3. However, it didn't work for me even with -std=c++11 in cxxflags.

Literally tried everything in #122 , but nothing worked for me. It always ended up with the same output.

My icu4c version 74.2

I think #179 solves this.

[alexrogers]

I'm having the same issue with Sonoma (14.5) installing 0.7.8 after upgrading ruby version to 3.3.3. However, it didn't work for me even with -std=c++11 in cxxflags.

exact same issue as @em1l1o for me except Ruby 3.3.1. I'm able to get 0.7.7 installed with gem install charlock_holmes -v '0.7.7' -- --with-icu-dir=/usr/local/opt/icu4c but no matter how i pass in c++11 (or 17 flags) the error remains the same.

[stanhu]

The error from the logs above:

error: '__declspec' attributes are not enabled

This seems related to https://bugs.ruby-lang.org/issues/18616 with a workaround in ruby/ruby@0958e19.

What happens if you run irb and RbConfig::CONFIG['CFLAGS']? You should see -fdeclspec in the list:

irb(main):001> RbConfig::CONFIG['CFLAGS']
=> "-fdeclspec -O3 -fno-fast-math -ggdb3 -Wall -Wextra -Wextra-tokens -Wdeprecated-declarations -Wdivision-by-zero -Wdiv-by-zero -Wimplicit-function-declaration -Wimplicit-int -Wmisleading-indentation -Wpointer-arith -Wshorten-64-to-32 -Wwrite-strings -Wold-style-definition -Wmissing-noreturn -Wno-cast-function-type -Wno-constant-logical-operand -Wno-long-long -Wno-missing-field-initializers -Wno-overlength-strings -Wno-parentheses-equality -Wno-self-assign -Wno-tautological-compare -Wno-unused-parameter -Wno-unused-value -Wunused-variable -Wundef  -fno-common -pipe"
irb(main):002> RbConfig::CONFIG['CXXFLAGS']
=> "-fdeclspec"
irb(main):003> RbConfig::CONFIG['CC']
=> "clang"
irb(main):004> RbConfig::CONFIG['CXX']
=> "clang++"

[stanhu]

Also you can try installing static_holmes and see if that resolves your issue: #163 (comment)

[joshuapinter]

@stanhu Here are my outputs in IRB:

irb(main):001> RbConfig::CONFIG['CFLAGS']
=> "-fdeclspec -O3 -fno-fast-math -ggdb3 -Wall -Wextra -Wextra-tokens -Wdeprecated-declarations -Wdivision-by-zero -Wdiv-by-zero -Wimplicit-function-declaration -Wimplicit-int -Wpointer-arith -Wshorten-64-to-32 -Wwrite-strings -Wold-style-definition -Wmissing-noreturn -Wno-cast-function-type -Wno-constant-logical-operand -Wno-long-long -Wno-missing-field-initializers -Wno-overlength-strings -Wno-parentheses-equality -Wno-self-assign -Wno-tautological-compare -Wno-unused-parameter -Wno-unused-value -Wunused-variable -Wmisleading-indentation -Wundef -fno-common -pipe"
irb(main):002> RbConfig::CONFIG['CXXFLAGS']
=> "-fdeclspec"
irb(main):003> RbConfig::CONFIG['CC']
=> "clang"
irb(main):004> RbConfig::CONFIG['CXX']
=> "clang++"

I don't think it matters, but this is with my Gemfile pinned to 0.7.7.

[stanhu]

@joshuapinter Ok, can you try running gem install static_holmes to see if that builds? If that's the case then #179 would solve your issue.

@alexrogers
My problem solved by reinstalling and upgrading xcode command tool.
sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install
softwareupdate --all --install --force
