<br>
I had apparent success installing Idris in this manner. (I even managed to get Emacs idris-mode up and working, which seems like a minor miracle given my abilities.) But after restarting my computer, it seems Idris is gone! No REPL; Emacs idris-mode highlights text as you type but cannot find Idris to load the buffers. Typing "idris" in the command line gets you<br>
<br>
idris: command not found<br>
<br>
...In response I tried<br>
<br>
cabal install idris<br>
<br>
...again, wherein I got<br>
<br>
Resolving dependencies...<br>
All the requested packages are already installed:<br>
idris-1.3.1<br>
Use --reinstall if you want to reinstall anyway.<br>
<br>
...How strange! Well I did<br>
<br>
cabal install idris --reinstall<br>
<br>
...and received<br>
<br>
Resolving dependencies...<br>
In order, the following will be installed:<br>
idris-1.3.1 (reinstall)<br>
Warning: Note that reinstalls are always dangerous. Continuing anyway...<br>
Configuring idris-1.3.1...<br>
Building idris-1.3.1...<br>
<br>
...where things stand, apparently midprocess with no further messages, to this minute. What accounts for the strange behavior? Should I be concerned?<br>
<br>
<br>
<br>
<br>
----------<br>
<br>
...Update!<br>
<br>
The install is FINALLY complete after all these hours! I got the following error messages:<br>
<br>
Installed idris-1.3.1<br>
cabal: Error: some packages failed to install:<br>
Agda-2.5.3 failed during the configure step. The exception was:<br>
ExitFailure 1<br>
<br>
...That is indeed the version of Agda I'd had; but I've tried opening and loading an .agda file into Emacs and so far (haven't tried other commands yet) all seems well. Also called up the Idris REPL and everything seems in order there too.<br>
<br>
Is everything indeed fine? Why the error messages? What has happened exactly?<br>
<br>
...A huge list of apparently success indicating messages...but then a couple of (apparent) error messages towards the end:<br>
<br>
Configuring Agda-2.5.3...<br>
Failed to install Agda-2.5.3<br>
<br>
[...]<br>
<br>
Configuring Agda-2.5.3...<br>
setup: The program 'alex' version >=3.1.0 && <3.2.0 || >=3.2.1 is required but<br>
it could not be found.<br>
cabal: Leaving directory '/tmp/cabal-tmp-14275/Agda-2.5.3'<br>
<br>
[...]<br>
<br>
Building idris-1.3.1...<br>
<br>
...where it has been stuck for probably half an hour now. Did the fact that I still had Agda open during this process have something to do with it? It hadn't been obvious to me that I should close it; I just thought the "Agda" in the command you sent me was a flag to avoid Agda or something, not a reinstallation as I now think it may have been. What should I do now? I'm starting to think that this is not normal! Idris shouldn't take this long to install!<br>
