    <p>Whatever I try to compile in Cygwin I get the following output:</p> <pre> checking for mingw32 environment... no checking for EMX OS/2 environment... no checking how to run the C preprocessor... gcc -E checking for gcc... gcc checking whether the C compiler (gcc ) works... no configure: error: installation or configuration problem: C compiler cannot creat e executables. </pre> <p>The last few lines of the logfile look like this:</p> <pre> configure:2810: checking for EMX OS/2 environment configure:2822: gcc -c conftest.c 1>&5 configure: In function `main': configure:2818: error: `__EMX__' undeclared (first use in this function) configure:2818: error: (Each undeclared identifier is reported only once configure:2818: error: for each function it appears in.) configure: failed program was: #line 2815 "configure" #include "confdefs.h" int main() { return __EMX__; ; return 0; } configure:2838: checking how to run the C preprocessor configure:2859: gcc -E conftest.c >/dev/null 2>conftest.out configure:2943: checking for gcc configure:3056: checking whether the C compiler (gcc ) works configure:3072: gcc -o conftest conftest.c -llib 1>&5 /usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: cannot find -llib collect2: ld returned 1 exit status configure: failed program was: #line 3067 "configure" #include "confdefs.h" main(){return(0);} </pre> <p>This is a fresh Cygwin install with G++ and a bunch of other devtools added. Any idea what I need to do to get this thing working? </p> <p>Update 0: Nick, your link to <a href="http://www.geektimes.com/linux/troubleshooting/c-cant-create-executables.html" rel="nofollow noreferrer">http://www.geektimes.com/linux/troubleshooting/c-cant-create-executables.html</a> was tried already - unfortunately this instructions are for redhat and do not seem to apply to cygwin. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
