eclipse - GNU Make Incremental Build: Force rebuild of specific file -

-

i'm using eclipse (juno) + cdt on windows 7 drive gcc, automatic makefile generation. worked great until used gcc's __date__ , __time__ preprocessor macros add build date/timestamp in project configuration header file.

on clean build, these macros work great - on incremental build, make doesn't rebuild associated object file; jumps straight linking.

i tried doing windows equivalent of touch pre-build step (described here: https://stackoverflow.com/questions/51435/windows-version-of-the-unix-touch-command) make still skips file. tried "touch" source file includes header; still no dice.

how can tell make rebuild files depend on particular header, on incremental build?

mark header .phony. ensure considered not date:

.phony: particular_header.h

Line ending issue with Mercurial or Visual Studio -

-
i seem have strange issue caused either visual studio or mercurial. localised single project, i'm guessing in project configuration causing issue. at difficult specify point, when perform action in visual studio, update every line ending in given file, means when @ file in sourcetree, every line has changed. i can replicate using nuget add package dependency; packages.config entirely replaced. if commit changes, including line endings, later same issue occur. workaround have shelve changes , reapply them, whereupon lines written correctly. i'm not sure application blame here. did make mistake of allowing sourcetree change mercurial configuration, issue have fixed, i'm not sure if has persisted. i thought might issue mercurial.ini files or hgrcs don't seem contain untoward. here's mercurial.ini [ui] username = ....

-
i have numeric variable, k=3.5e-5 (its values calculated throughout script). want write value somewhere (title, text in plot, etc) in plot as: k_{root} = 3.5 10^{-5} cm /d i have tried functions bquote , substitute , no 1 worked. let's put question in examples. have tried following: 1) png("exp_1.png") kroot = 3.5e-5 plot(1:10,1:10, text(4,9,bquote(italic(k[root])~"="~.(kroot)~"cm/d"))) dev.off() try favorite function, paste(). plot(1:10,1:10, text(4,9,gsub("e",paste("k[root]=",format(k,scientific=true),"cm/d",sep=" "),replacement=" 10^"))) you can replace "e" here using function gsub. i've edited answer include this. the output: > k=.0000035 > k [1] 3.5e-06 > gsub("e",paste("k[root]=",format(k,scientific=true),"} cm/d",sep=" "),replacement=" 10^{ ") [1] "k[root]= 3.5 10^{ -06 } cm/d"...
