Bless you

Ohhh my god I see now

I'm not sure if I follow on that last statement

The equation and initial conditions I have are x'' + 30.61x' = e^(-.2t); x'(0) = 0; x(0) = 0

as with the general solution alone, I'd only have two equations (one for x(0) and one for x'(0)), which is not enough to solve for 3 unknowns

It seems to be doable, as WolframAlpha solved it, but I'm wondering if I can use the solutions separately to solve for the constants instead of using just the general solution

In differential equations, the homogeneous and particular solution are both independently solutions, and I have a problem where I have three constants to solve for but only two initial conditions

I've gotten down to a general solution with three unknown constants, but I only have two initial conditions, and I'm wondering if I can separately solve for the constants in the two solutions

In diff eq, I know the homogeneous and particular solutions are both independently solutions as well as together

I am in quite a pinch, as I have an assignment due soon and a brainfart to go along with it

So I hear there are some mathematically inclined folks in here

I'll try U&L

Yes

Would it be more appropriate on SO or U&L?

I don't know if it's worth asking a question, but I guess I could

Says its missing "Demangle"

Or at least, LLD

Trying to compile LLVM

Anyone familiar with CMake?

I get Library `Demangle' not found in list of llvm libraries.

Trying to compile LLD

Anyone familiar with Cmake/llvm?

So I'm assuming it's something that has to be compiled along with the rest of LLVM's stuff

Because I used the package manager to get LLVM, and there is no tools directory anywhere.

It says to put it in llvm's tools directory.... does that mean I need to manually compile all of LLVM?

So uh... anyone familiar with compiling lld

Site says put it in LLVM's tools directory, but I don't know where that'd be. Not in /etc/llvm

Backticks don't do monospace on here? dang

` llvm-config failed with status Permission denied`, and I'm running it as root.

ugh. What would the target name be?

Oh right, it uses CMake

not sure what exactly

Been having trouble compiling that

Oh and it looks like I do need LLD

so I'd have to go through the god-awfully long process of getting that

Although I recently reloaded windows

ah "from an installation of Visual Studio"

I don't think uncompiled code would be hanging around

well nevermind

I mean, I suppose I could get the sysroot from my own windows system somehow?

You'd think, claiming to be a cross-compiler, Clang would come with a sensible default sysroot for windows

Although, where would I get that?

Aha, exactly what I was thinking

nope

mmm... hope

When you don't specify an ABI or specify one that doesn't exist, it defaults without any sort of message, which kinda sucks

I think at least. haha

and the last part of the triple is the abi

although I don't know what ABI windows uses.

I was using --target x86_64-win32-
