Different output for make release vs. g++

[radhikamattoo]

I've been using the g++ command to run my code, and when I do it seems to run fine, but when I try to use make with the release option for faster computation, I get completely different outputs.

When I run g++ src/main.cpp -I ext/eigen then ./a.out my code runs like expected.

When I run (within the build directory) cmake -DCMAKE_BUILD_TYPE=Release ../ then make then ./Assignment1_bin I get different errors each time I try. Sometimes I get:

Assertion failed: (nbRows >= 0 && (RowsAtCompileTime == Dynamic || RowsAtCompileTime == nbRows) && nbCols >= 0 && (ColsAtCompileTime == Dynamic || ColsAtCompileTime == nbCols)), function CwiseNullaryOp, file /Users/mattoor/Desktop/School/Graduate/Computer Graphics/homework/assignment-1-radhikamattoo/ext/eigen/Eigen/src/Core/CwiseNullaryOp.h, line 63.
Abort trap: 6

Sometimes I just get:
Segmentation fault: 11

Other times my code runs, but doesn't detect any intersections at all and just outputs a black image.

Is there any way to stop this? Why am I getting different errors? My current code is in my repo.

Hi,

I tried to run your code. The reason that it's different is that your executable is in a different location, and so the path of off isn't able to be found. So your function for readOFF fails and your subsequent operations produces a memory violation.

Best,
Zhongshi

No, I don't think it's normal. It's probably that there's an infinite loop in your program and takes infinite time. In order to debug, I suggest you to print more debug info when running the program, so you can know where is taking significant time and track down the potential bug. Also, I recommend to use `std::cerr` instead of `std::cout` for debug printing purpose. Best, Zhongshi

I'm currently implementing a single mesh for 1.4, just to see if my algorithm is correct, but it's taking an *extremely* long time to run. I've set the CMAKE_BUILD_TYPE flag set to Release, but it's still taking on the scale of several hours - I started running it last night, and it is still not finished. Is this normal? — You are receiving this because you commented.
