Debian

When running Android Studio 2.3.1 on Linux, there may be a link error along these lines:

cmake android libssl.so.1.0.0: cannot open shared object file: No such file or directory

This is due to more recent versions of openssl being installed, but for some reason this version is hard coded into CMAKE and Android Studio.

The solution is along these lines for a Debian system:

sudo apt install build-essential
wget https://www.openssl.org/source/old/1.0.0/openssl-1.0.0t.tar.gz
tar zxvf ../openssl-1.0.0t.tar.gz 
cd openssl-1.0.0t/
./config -fPIC shared zlib-dynamic
make 
sudo cp libssl* /usr/local/lib/
sudo cp libcrypto* /usr/local/lib/
sudo ldconfig

When attempting to run the 'IQ - News' application supplied with the DTN/IQFeed client in Wine on a Debian Linux box, the following may occur:

#:~/.wine/drive_c/apps/IQFeed$ WINEARCH=win32 wine News.exe
Could not load wine-gecko. HTML rendering will be disabled.
err:mshtml:HTMLDocument_Create Failed to init Gecko, returning CLASS_E_CLASSNOTAVAILABLE
err:mshtml:HTMLDocument_Create Failed to init Gecko, returning CLASS_E_CLASSNOTAVAILABLE
err:mshtml:HTMLDocument_Create Failed to init Gecko, returning CLASS_E_CLASSNOTAVAILABLE

The same issue may occur when running:

wine iexplore

The fix appears to be simple. Determine your version of wine with:

# wine --version
wine-1.8.7 (Debian 1.8.7-2)

Then go to WineHQ Gecko, download the 32 bit version of the appropriate wine_gecko.msi if you are running on a 32 bit system, or both the 32 and 64 bit version when running on a 64 bit system. As the instructions on that page indicate, place the downloads into /usr/share/wine/gecko. You may need to 'mkdir /usr/share/wine/gecko' first.

News and iexplore now function as expected.

As one more addition, there is one more trick for installing DTN/IQFeed on a 64 bit Debian Linux system:

apt install wine
dpkg --add-architecture i386 && apt-get update && apt-get install wine32   
apt install winetricks
WINEARCH=win32 winetricks -q vcrun2012
