Compilation Error on Mac Snow Leapord with GCC 4.7 about pdf2htmlex HOT 25 CLOSED

You can easily compile it without gcc/g++ on mac. Make sure your xcode is upto date and then use make && sudo make install.

Just looking at error I can assure you that your default gcc/g++ is not 4.7. Please run gcc -v and if it's the case then export proper compiler before compiling if you dont wants to use LLMV compiler.

Can you find anything about "c++0x" in 'man g++' ?

@coolwanglu the preprocessor options are below from the "man g++"

what exactly do you require me to find ? I have a huge man for g++. I installed gcc47 from macports, the commandline fails as "-std=c++0x" is not a valid compile time arg.

from pdf2htmlex.

not --version but -v

just search c++0x, or checkout if there's c++0x listed under -std=

Oh I see it should have been dropped starting from 4.7

Can you please try replace all c++0x with c++11 in CMakeList.txt

I will add a condition later

still does'nt work after converting/replace all with c++11 check the error log below :

the error appears also on the gcc version 4.4.7. I changed the gcc version and tried but its still throwing the same error

Is CMake actually using GCC?
And how about the manpage?

Or can you compile a simple cpp file with g++ --std=c++0x ?

std::round should be in since c++11, seems it is not in gcc 4.4.7?

as a workaround you can define round as floor(x+0.5);

I'll fix it later

Also, your /opt/local/bin/gcc is GCC 4.4.7 as you can see in cmake log. Force C and CXX compiler to 4.7 in cmake.

@coolwanglu what is 'x' in floor(x+0.5) ?? am i missing something ?

from pdf2htmlex.

I mean implement a simple round function, in case there's no std::round.

I guess it'll be fine if you use 4.7

I just replaced floor instead of round and seems to work fine. I dont know what is the purpose of the text.cc :)

I used the following func :

int round(double number)
{
return (number >= 0) ? (int)(number + 0.5) : (int)(number - 0.5);
}

from pdf2htmlex.

The code compiled and executed fine. I also tried converting a simple pdf to html and it worked fine. :) I want to convert the html back to pdf once again...!! after manupulations on the html. Is it possible ??

from pdf2htmlex.

Glad to hear that!

And you'll need another tool to convert html to pdf.

Hi Everyone,

i am having the EXACT same issues building it from macports. i am trying to follow the steps mentioned in the discussion here. but being a newbie i have difficulty understanding where the cmakelists.txt file is and all the other compiler settings that need to be changed. can somebody help me out with this and for the benefit of everyone who might use macports to install pdf2htmlEX, provide a workaround for this issue?

Thanks!

from pdf2htmlex.

@lts205 what's the compiler you are using, and what's the version?

from pdf2htmlex.

hi coolwanglu,

i finally got it to install, just used the "build from source" instructions on the "code" tab. but still i had issues when using gcc42. i then installed mp-gcc47 and made it active with the instruction sudo port select --set gcc mp-gcc47. after this the installation "build from source" went smooth.

as for your question i was using gcc42 which i guess came along with my xcode 3.2.6, latest macport version. so i tried to build it with macports but i got the exact same failure as discussed in the forum above which did not change after i installed gcc47 and made it active. maybe i missed something obvious.

btw awesome tool :D

from pdf2htmlex.

@lts205 gcc42 is too old to be supported, as there are quite a few c++11 features being used.
@iapain is it possible to add a dependency on higher versions of GCC in MacPorts ?

from pdf2htmlex.

@coolwanglu We should do all these checks in CMakeList instead of Portfile or BrewFormula.

from pdf2htmlex.

What I meant is, for MacPorts or Brew, I may even remove the CMake files,
as long as there's a valid Makefile(with no check), and proper dependencies
in Ports/Brew, the user will be able to install it.

If I add the check in CMakeList, I think MacPorts users may ask why still
it cannot compile, or why they have to install gcc manually.

What do you think?

Your point is valid if we see compiler as dependency. To me compiler is very important asset, I hate when some program updates or override my compiler settings. Well, you decide. I can inject proper compiler dependency. For those who have properly installed Xcode (with all updates) will never be an issue.

from pdf2htmlex.

I added in CMakeLists.txt, and I'm expecting new complains about this.
