For example, some build procedures use CFLAGS when compiling .c to .o, but not when linking .o files together into an executable. The most reliable way I've found of getting -g set everywhere is to make it part of $CC. (It is at least somewhat important that the compilers I use ignore -g, rather than erroring out, when doing something for which it's not relevant.) I've even occasinoally run into some that don't provide a way to set CFLAGS, or make it obscure and undocumented enough that they might as well not. >> So if I'm going to end up building 2.9.0dev.10, I'm going to have to >> resurrect the kludge I used before: create a script (I called it >> cc-g) that runs cc -g "$@", and tell configure to use that. > I do that for compiler warnings, but not for optimization/debugging. For routine use, I do too: I have a script, wgcc, that runs gcc with a suitable set of options depending on the particular compiler/version in use. For example, one of the more heavily used of the lists of flags is -Werror -W -Wall -Wpointer-arith -Wcast-qual -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wno-uninitialized -Wno-sign-compare -Wno-missing-field-initializers -Wno-pointer-sign -Wno-format-zero-length. I don't always want -g, but I often do. When I was building that lynx, performance was very much secondary to debuggability. > I do this with all C programs - lynx isn't special in that regard.

Re: [Lynx-dev] lynx word bleeding?
Hi Ian, yes we have been here before. Still, I doubt creating my own lynx.dfg file will fix my greater issue, why this new compile of lynx locks up if Attaching a file, or sending an email with an attachment in my basic gmail account now. It also does not allow for some kinds of downloads in that account either. It is not gmail doing it, I get a 408 time out error, but can send things just fine using the older edition of lynx we have here.

[Lynx-dev] configure-script issue
I wrote, earlier today, of trying to rebuild a past lynx install, saying > This led me to rediscover that the configure script for that version > appears to be broken. I fetched the current .tar.bz2, which unpacked into lynx2.9.0dev.10. Turns out the configure script is still broken, just in a trivially different way. (Aside from all the ways that inhere in using configure scripts at all, that is.) Specifically, when I run it with CC set to cc -g, in order to get -g on all compiler runs, the configure script calls this broken. The old script then claimed this was a misuse of $CC. The modern script doesn't call it _mis_use, but it does still - like the old one - complain and pull the -g off $CC and put it...somewhere else; configure code is sufficiently twisted I'm not entirely sure where. So if I'm going to end up building 2.9.0dev.10, I'm going to have to resurrect the kludge I used before: create a script (I called it cc-g) that runs cc -g "$@", and tell configure to use that. But this leads me to ask: why do this? Is there something wrong with wanting a specific option on _all_ cc runs? Or is there some other way to specify that? Doing this has worked with every other such thing I've tried, and it strikes me as remarkably obnoxious for the script to think it knows better than I do how the compiler should be run in my environment, forcing me to workarounds such as the cc-g script I sketched above. (I notice other examples of this, such as the way it maps c[1-9][0-9] to clang with some option, if clang is detected; fortunately, I'm not trying to use clang, so I can ignore that in practice - but there certainly are plenty of ways it could cause the build to break when just using what the user told it to would work.) But lynx is so sane in so many other respects this quite stands out, leading me to ask what's behind it and why the complaint doesn't explain either why it's a bad idea to want to specify options on all cc runs or what the correct way to do so is. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTMLmo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
[Lynx-dev] Source source?
Some time ago, I set up then-recent lynx on a Linux machine (at work, of course) - the lynx install I used for the gmail use I mentioned recently. Today, I had occasion to copy this to another Linux machine. Because they're different ISAs, I had to rebuild. This led me to rediscover that the configure script for that version appears to be broken. So I tried to git pull. The repo I cloned to get that version was git://anonscm.debian.org/pkg-lynx/lynx.git. But anonscm.debian.org refuses the connection when I try to pull from there now. And I wouldn't expect a debian.org repo to be authoritative for lynx in any case; I no longer recall why I used it then. For the moment, I've just fetched the .tar.bz2.

This is why having your own version of lynx.cfg in your home directory and calling it helps with individual preferences.
