This was a build that had been working in the past. Here's output from the link stage. I've included linker output and the relevant portions from the .pro file.

• Manual setup on Mac OS X (10.13 - 11.0). Ld: library not found for -lssl. Devel openssl-devel ImageMagick ImageMagick-devel mysql-devel postgresql-devel.
• 解决库移位出现的 ld: library not found for -lXXX. 在Pod里，有个第三方库不更新了，但是里面的警告挺多的，开发组老大让我把它单独挪出来，把警告处理掉，期间遇到了一个坑，于是就有了这篇文章。 如约，Pods工程目录下，把Posfile里的那个库注释掉，然后： pod install.

$ brew mysql install ・再度pipを実行すると、以下のエラ〜メッセージが発生。 エラ〜メッセージの内容が変わったので、1個解決したようである。. Update Django ’ s database connection to connect to MySQL in settings.py. Ld: library not found for -lssl while trying to install. Are still not set.

Linking is reporting ld: library not found for -lssl

I added -L/usr/lib to the .pro.

-rwxr-xr-x 1 root wheel 32928 May 27 19:24 /usr/lib/libssl.dylib

Running the build manually (cut & paste) produces the same error.

This is pretty well-trodden territory, but I have recently setup several static sites on AWS, using S3 + Cloudfront, and I thought it would be nice to document the process. The setup isn't hard, but there are lots of steps, and you have to do most them in the right order …

This isn't news to anybody, but using pyenv to manage virtual environments for Python is great. The python packaging and module system is really annoying, but pyenv makes it tolerable enough that I felt like writing it down.

Setup is pretty simple. You basically need to:

1. Install pyenv itself
2. Install …

Today I migrated this blog to use Pelican, a python-based static site generator.

On the whole, the setup was pretty easy, but I hit a few snags setting up the theme.

This is how I installed on a Mac

First, get a clean python environment

A very frustrating thing in the legacy system at work is that error logging is badly busted. Because the system is fragile and can't suffer significant downtime, I am disinclined to apply any dramatic fixes. However, I found a pretty cool PHP module that offers a partial solution:

Ran into a very interesting bug recently.

In an Order Management System, it was becoming increasingly apparent that certain orders failed to be completely processed, leaving them in a 'this should never happen' incomplete state. For awhile there seemed to be no rhyme or reason to it - just absolutely no …

A situation I've encountered twice now is the need to serve a site's content from a subdomain using a different Wordpress Theme. In the first case, the subdomain was a mobile site and the alternate theme was optimized for mobile with a simplified layout and fewer images. In the second …

Ld Library Not Found For Lssl

A recent project required cross-posting content between two sites. To avoid duplicate content issues, we're using rel='canonical' to indicate which post is the original and which is the duplicate. While not 100% ideal, evidently cross-domain rel canonical is an okay thing to do.
